How do adjustable dumbbells compare to traditional weights. What makes the ProForm SpaceSaver Dumbbell stand out among competitors. Why should you consider investing in adjustable dumbbells for your home gym.
Understanding Adjustable Dumbbells: A Space-Saving Solution for Home Gyms
Adjustable dumbbells have revolutionized home workouts by offering a compact and versatile alternative to traditional weight sets. These innovative fitness tools allow users to quickly adjust the weight load without the need for multiple dumbbells, making them ideal for small spaces and varied workout routines.
The ProForm SpaceSaver Dumbbell, available on Amazon, is a prime example of this space-efficient design. But how does it compare to other adjustable dumbbells on the market? Let’s dive into the world of adjustable weights and explore the features that make the ProForm SpaceSaver stand out.
Key Features of the ProForm SpaceSaver Dumbbell
The ProForm SpaceSaver Dumbbell boasts several features that cater to fitness enthusiasts looking to maximize their workout potential in limited space:
- Adjustable weight range up to 25 pounds
- Compact design for easy storage
- Quick weight adjustment mechanism
- Durable construction for long-lasting use
- Ergonomic handle for comfortable grip
These features combine to create a versatile piece of equipment that can adapt to various exercises and fitness levels. But how does the ProForm SpaceSaver compare to other top-rated adjustable dumbbells?
Comparing ProForm SpaceSaver to Top Competitors
While the ProForm SpaceSaver Dumbbell offers impressive features, it’s essential to consider how it stacks up against other popular adjustable dumbbells:
ProForm SpaceSaver vs. Core Home Fitness Adjustable Dumbbell Set
The Core Home Fitness set is known for its rapid weight adjustment from 5 to 50 pounds. How does the ProForm SpaceSaver compare in terms of adjustment speed and weight range?
While the ProForm SpaceSaver offers a more limited weight range (up to 25 pounds), it may be more suitable for beginners or those focusing on lighter weight, higher repetition exercises. The Core Home Fitness set, with its broader range, caters to a wider variety of fitness levels and exercise types.
ProForm SpaceSaver vs. MX Select MX55 Rapid Change Adjustable Dumbbells
The MX Select MX55 features a unique adjustment mechanism with a release button and separate knob. How does this compare to the ProForm SpaceSaver’s adjustment system?
The ProForm SpaceSaver likely offers a simpler adjustment process, which could be advantageous for quick transitions between exercises. However, the MX Select MX55’s higher maximum weight capacity may appeal to more advanced lifters.
ProForm SpaceSaver vs. Bowflex SelectTech 552 Dumbbells
Bowflex’s SelectTech 552 allows for more precise weight increments. Is this level of customization necessary for most users?
While the Bowflex offers more granular weight adjustments, the ProForm SpaceSaver’s simpler design may be sufficient for many users, especially those new to strength training or working with lighter weights. The ProForm’s potentially shorter length could also make it more manageable for certain exercises compared to the Bowflex’s longer bar.

FYI
Whether you’re looking to build some muscle or add a new twist to your workout routine, adjustable dumbbells are a more compact (and usually less expensive) alternative to a full rack of traditional weights.
After lifting thousands of pounds and completing hundreds of reps, we recommend Core Home Fitness’s Adjustable Dumbbell Set—which can go up to 50 pounds faster than you can sneeze—as the best set for at-home use.
Weight increments
Some adjustable dumbbells can be loaded in 5-pound increments, others can be dialed in at changes of 2.
5 pounds.Size
Longer dumbbells can make certain exercises more difficult to perform.
Composition
Adjustable dumbbells and their cradles are made of various materials; metal generally lasts longer than plastic.
Warranty
We looked for sets with at least a two-year warranty for parts, which is standard for free weights with moving parts.
5 pounds.Our pick
Lifting weights is not always easy, but the Core Home Fitness Adjustable Dumbbell Set provides a lot of simplicity and can go from 5 to 50 pounds with just a twist of a handle. The weights are also a manageable length, and they get shorter—and therefore more ergonomic to handle—as you reduce the load.
Our complaints about these dumbbells are minor: The weight increments are 5 pounds (rather than the 2.5 pounds found on some others). And like most adjustable dumbbells we tested, the weights require careful alignment to rerack them.
The racks sometimes stick when you pick up these weights fully loaded, but the Core Home Fitness model still offers the best, easiest-to-use experience in its price range, making it a great choice for most home gyms.

Runner-up
The MX Select MX55 Rapid Change Adjustable Dumbbells come with two handles affixed with two permanent plates, starting you off at 10 pounds. Nine additional plates are stored on each side of a cradle, and weight is added to the handles through a distinct process. You press a release button on each side of the handle, which allows you to turn a separate knob on the top of the handle. Choose your desired weight, press down the knob, and lift up the dumbbell for use.
Although this is done fairly quickly, it’s not as fast as adjusting the Core Home Fitness set. But just like with the Core Home Fitness dumbbells, you have to carefully align the handles back into their cradles—the plates have a ridged design that connects like a puzzle piece into the next plate in line.
Also great
Bowflex SelectTech 552 Dumbbells
These sturdy dumbbells allow subtler load adjustments, but their length can make some exercises more difficult, and the weights don’t feel as sturdy as our top pick.
The Bowflex SelectTech 552 Dumbbells adjust smoothly from 5 to 52.5 pounds when you turn dials at either end of each weight. With 2.5-pound increments for the first 25 pounds (and 5 pounds thereafter until you get to 52.5 pounds), these Bowflex weights allow for more nuance in training progressions than our top pick. (A 5-pound increase can feel significant, particularly at lower loads, which could be challenging for novice lifters.) However, the 15.75-inch-long bars don’t get shorter as you change weights, making this set a bit harder to handle, especially for smaller-framed people. The long bars also make some exercises difficult.

Who this is for

Lifting weights isn’t some trending social media fitness fad or a hobby reserved for bodybuilders in muscle shirts gulping creatine. Resistance training confers a host of health benefits including protecting joints from injury.
The US Department of Health and Human Services’s Office of Disease Prevention and Health Promotion recommends (PDF) that American adults complete a minimum of two muscle-strengthening sessions per week. Such regular training can pay huge (no pun intended) dividends. “Engaging in one hour of resistance training every week has the ability to lower your risk for metabolic syndrome or even cardiovascular morbidity,” said exercise physiology and nutrition expert Nathaniel Jenkins.
One way to reach those goals is to use free weights such as standard dumbbells or kettlebells. (Resistance bands can also do the trick.) But as you get stronger, you’ll find that you need to add more weight (or resistance) to achieve the maximum benefits. “The only reason the body adapts is because it’s challenged beyond its present capacity,” exercise scientist Brad Schoenfeld told us. “If the weights are too light, you can’t do that.”
If you’re committed to weight training at home, investing in a set of adjustable dumbbells—two handles that each allow you to load them incrementally with weights usually totaling up to 50 pounds or more—can save you money and space.
A full set of traditional dumbbells can be prohibitively expensive and require the same amount of storage space as a small bookcase.
Up to 50 pounds per dumbbell may seem like a lot of weight. But even a novice exerciser is usually capable of deadlifting a load equal to their body weight for at least one rep after proper training, so 50 pounds per weight ends up making sense for most people. If you’re an experienced lifter and you would like more than 50 pounds per dumbbell, we have recommendations for you, too.
How we picked and tested
Photo: Michael Murtaugh
In evaluating adjustable dumbbells, we prioritized the following:
- Adequate load: We looked for per-handle loads ranging from 5 or 10 pounds to 50 pounds, which offer enough versatility for most exercisers.
- Speed and ease of adjustment: Being able to load or unload weight quickly and smoothly is important for workout timing and flow, and also for safety.
- Adjustment increments: The typical load adjustment increment is 5 pounds, but some dumbbells allow increases or decreases of 2.5 pounds.
- Ergonomics: How the weights feel in your hands and how you can move while holding them is extremely important, especially given that these dumbbells are likely to be bulkier, longer, and more unwieldy than standard cast-iron dumbbells you’d find on racks at a gym.
- Overall construction: More metal (and fewer plastic) components may make for a safer, longer-lasting set. Some sets are coated with rubber or other materials to reduce sound and prevent rusting.
You can find a variety of mechanisms for setting loads on adjustable dumbbells, and we were mechanism-agnostic when deciding which models to test. The most common types are:
Traditional: You manually slide weight plates, held in place by a threaded screw collar, on or off a bar.
Dial: The dumbbells sit in a cradle, and you turn a dial at one or both ends, engaging or disengaging the plates you need.
The ones you don’t want remain in the cradle when you pick the dumbbells up.
Handle-twist: You rotate the handle to collect or disengage the weight plates from the center outward, with the unneeded plates remaining in the cradle when you pick the weights up.

We’ve tested 17 sets of adjustable dumbbells over the years. To test each set, staff writer Seth Berkman and supervising editor Ingrid Skjong worked out with them several times a week, doing a variety of exercises including curls, flies, rows, presses, raises, and deadlifts. We found that 2.5-pound increments were best for working out with lighter total per-dumbbell loads, while 5-pound increments could, depending on the exercise performed, require reducing the number of reps when increasing the per-dumbbell load.
We considered the ergonomics of using each set, particularly in maneuverability during exercises.
We took into account the length of each dumbbell at given loads. Longer bars mean that for certain exercises people with smaller frames may need to modify their range of motion, their body positioning, or both. These modifications, though not necessarily harmful, can affect which muscles are engaged and, potentially, the quality of the workout.
Finally, we looked for any safety or durability concerns. We noted the ratio of plastic to metal components and how secure the weights felt in terms of any rattle or movement of the plates, which many models produce to some degree. Most plated adjustable dumbbells run the risk of unselected plates sticking during load selection and potentially falling.
We also considered long-term testing feedback from people who’ve owned sets of adjustable dumbbells, including our picks, for years.
Our pick: Core Home Fitness Adjustable Dumbbell Set

Our pick
The Core Home Fitness Adjustable Dumbbell Set, our pick for four years running, continues to stand out from the competition with a fast and almost seamless workout experience.
They’re easy to adjust. Each dumbbell can be set to the desired weight—between 5 and 50 pounds—in seconds, even simultaneously, with a simple twist of the handles. For the other models we tested, adjustments took anywhere from four to 25 seconds per dumbbell.
They have a shorter length. Fully loaded, these dumbbells are a manageable 14.5 inches long, shorter than nearly all others we tested. When the weight is reduced, so is the dumbbell’s overall length (some models maintain the same bar length no matter how much weight you load them with). Shorter dumbbells mean that people with smaller frames don’t have to modify their range of motion or movement angles in order to avoid colliding the weights together in, say, an overhead military press (video).
The Core Home Fitness dumbbells are easy to set back in their cradle. Video: Michael Murtaugh
They have a comfortable rubber grip. Of all the sets we’ve tried, this one most closely resembles a rack at the gym.
A lot of individual dumbbells have metal knurled grips (think thousands of tiny bumps), which provide a more stable grip but can also cause calluses without the use of gloves and sometimes give off a metallic smell. The Core Home Fitness dumbbells have a composite rubber grip, which feels smooth and comfortable.
The weight plates are made of steel and are covered in a composite rubber. The cradle is aluminum and sturdy enough. Using the set three times a week, Seth (who is 5-foot-7) found these dumbbells were the easiest to use, and they contorted well for a variety of exercises that target different muscle groups, whether he was standing, sitting, or lying on a bench.
The company backs its weights with a two-year, parts-only warranty, standard for this category, and the price includes free shipping.
How the Core Home Fitness Adjustable Dumbbells have held up
Ingrid purchased a pair of the dumbbells directly from Core Home Fitness in late 2020 and has used them at least twice a week since then with few issues, save for their aforementioned tendency to stick to the cradle.
She uses them for goblet squats, single-leg deadlifts, overhead presses, rows, and farmer carries. Ingrid notes that nearly three years later, the adjustment mechanism continues to work without a glitch, and the handle grips still hold up.
Another tester who’s had the Core Home Fitness dumbbells for four years says her set is in fantastic shape with no issues. Cleaning is as simple as an occasional wipe down and vacuuming the cradle every so often. She also notes, though, a 2.5 pound add-on would make the gap between weights a little easier. “For smaller muscle groups (for example triceps) a 5-pound jump can be too much,” she says.
Flaws but not dealbreakers
The weight increments are fixed at 5 pounds. For some people (or certain exercises), a 5-pound jump can be a lot. If you prefer dumbbells that you can adjust in 2.5-pound increments, consider our runner-up or also-great pick.
The other small issues are ones that we encountered with most of the sets we tested: When the dumbbells are fully loaded, the cradles tend to stick to the outside of the weights as you pick them up.
(Keeping a toe on the cradle or picking the dumbbells up one at a time so you can hold the cradle with your other hand solves that problem.)
The Core Home Fitness dumbbells, like most other models we tested, also have to be aligned carefully for you to rerack them. As is the case for all the adjustable dumbbells we tested, you can’t drop these as you might do with regular free weights: You must put these down with a bit of care.
When fully loaded, the weights have a tendency to stick in the frames. Using your other hand or a foot on each rack is a good solution. Video: Michael Murtaugh
Runner-up: MX Select MX55 Rapid Change Adjustable Dumbbells

Runner-up
The MX Select MX55 Rapid Change Adjustable Dumbbells offer variety and may be particularly appealing to more-serious lifters.
Each handle comes preloaded at 10 pounds. You can technically lift in 2.5 pound increments, but not in an ideal method for beginners. For example, you can set a dial on one end of the handle to 25 pounds, while the other dial is at 20 pounds. You are then technically lifting 22.5 pounds, but with one end heavier than the other, which can be a bit unwieldy. However, experienced lifters might enjoy stacking one end with 5 to 10 pounds more weight to specifically train certain muscles using uneven loads.
The plates are made of steel and coated with polyamide nylon, which an MX Select representative said lowers noise and prevents rusting. The cradle, made of powder-coated formed steel, is sturdier than any other set we tested. (The company also sells a dumbbell stand for about $170.) The contoured handle provides a good grip.
The MX Select MX55 Rapid Change Adjustable Dumbbells require more care than most when returning the weights to their cradle. Video: Michael Murtaugh
Using these dumbbells at least three times a week, Seth noticed the bar felt sturdy and the weight adjustment system was easy to handle, even though it took a few more seconds than the Core Home Fitness Adjustable Dumbbell Set.
One minor flaw he noticed was that sometimes when switching between weights on the dial, it got stuck between two numbers (for example, 15 and 20) but it’s easy to readjust, and that only adds a second or two on the process.
You want to make sure the weights stacked in the cradle don’t have any gaps—they should be touching each other to create the maximum snugness when pulling the handle in and out (think of the compactness like placing books on a bookshelf). Like all adjustable dumbbell sets, you don’t want to slam these back into the cradle. And the MX55 dumbbells take more precision than others to set down.
Adjusting the MX55 dumbbells takes a bit longer than adjusting some other weights, but it’s still fairly quick and easy. Video: Michael Murtaugh
When you order from the company website, free shipping is included to the contiguous states.
These dumbbells come with a two-year limited warranty.

Also great
Bowflex SelectTech 552 Dumbbells
These sturdy dumbbells allow subtler load adjustments, but their length can make some exercises more difficult, and the weights don’t feel as sturdy as our top pick.
The Bowflex SelectTech 552 Dumbbells accept adjustments in increments of 2.5 pounds for the first 25 pounds, and 5 pounds after that until you reach 52.5 pounds. You select loads by turning a dial at each end of the dumbbell—we liked that it made a sound, not unlike a bicycle bell, to indicate each new weight level. Doing so takes only six or seven seconds, but that’s more than twice as much time as on our top pick from Core Home Fitness.
Regardless of how much weight you load, the bars remain nearly 16 inches long—longer than our other picks. For testers who are under 5-foot-5 and narrow-shouldered, the length of the Bowflex weights sometimes felt unwieldy and affected body positioning and ranges of motion in some exercises.
The Bowflex SelectTech 552 dumbbell (top) is the longest of our picks. Here, all three dumbbells—from Bowflex (top), Core Home Fitness (center), and MX Select (bottom)—are adjusted to 20 pounds. Photo: Michael Murtaugh
As with most adjustable dumbbell sets, the racking cradle can stick when you’re lifting a full load, and you need to have the weights aligned carefully to rerack them.
Unlike other models, non-consecutive plates are left in the cradle with certain weight levels (for example, the second, third, and sixth plate), making precision in reinsertion even more important).
Like our top pick, these weights come with a two-year, parts-only warranty. The company also offers extended, parts-only policies and free shipping.
Other good adjustable dumbbells
If you’d prefer dumbbells with steel plates and a minimalist style: You might like the Smrtft Nüobell 50-pound set, which has the feel of traditional dumbbells—steel plates (with plastic components), knurled metal handles—and a sleek look. Each dumbbell adjusts in 5-pound increments with a twist of the handle. But these dumbbells typically cost about $200 more than our picks from Core Home Fitness and MX Select.
The competition
We didn’t test the Bowflex SelectTech 1090 Dumbbells, which range from 10 to 90 pounds each in 5-pound increments and go for about $800.
At a whopping 17.5 inches long—nearly 2 inches longer than the Bowflex SelectTech 552 Dumbbells—they’d likely affect almost anyone’s range of motion.
You can adjust the Merax Deluxe 55 Pounds Adjustable Dumbbells similarly to our top pick: by twisting their handles. But the set goes from 15 pounds to 55 pounds in significant 10-pound increments (our top pick progresses by 5-pound jumps), so we decided not to test it.
The Mtn Gearsmith Adjustable Dumbbells, with their traditional collar-and-weight-plate design, are very similar to the Yes4All Adjustable Cast Iron Dumbbells we tested but typically cost more (see below). We chose not to retest them.
The NordicTrack iSelect Voice-Controlled Dumbbells are unique in that they can be changed using, yes, voice commands. We previously tested the dumbbells by connecting them to a third-generation Amazon Echo Dot provided by NordicTrack. Though it was responsive to our commands (“Alexa, change the weight to 35 pounds”), we found that the dumbbells were more quickly and easily adjustable by hand (using their manual dials).
PowerBlock adjustable dumbbells are a solid choice, but some people may be deterred by their boxy shape, which past testers described as like “reaching into a toaster.” We’ve tested three different sets of PowerBlock weights over the years, including, most recently, the PowerBlock Elite USA 5-50 Stage 1 Set, which goes from 5 to 50 pounds in increments of 5 pounds, with the ability to increase by 2.5 pounds with a pair of supplemental cylindrical adder weights. You can adjust this set with a two-pronged selector pin attached to an elastic cord. Loads are color coded; the corresponding weights are printed on the top of each dumbbell. The process isn’t difficult, but it can be finicky and is a touch more labor-intensive and time-consuming than a handle-twist or dial mechanism. These dumbbells are more compact than other models, and PowerBlocks are known for their durability. The Elite USA 5-50 Stage 1 Set has a five-year limited warranty—three years longer than those of Core Home Fitness and MX Select.
(The company makes it clear that its warranty covers only PowerBlock sets purchased from PowerBlock or an authorized retailer.)
Tempo Core combines traditional adjustable dumbbells with connected workouts. Sets start at about $245 and include 50 pounds of adjustable weights (a variety of stainless steel plates and collars can be purchased separately). The dumbbells can be used for any activity but are intended for use with Tempo’s interactive exercises, which can be accessed for a monthly subscription of about $39. We did not test the Tempo dumbbells.
If you don’t mind taking a longer rest between exercises, consider the Yes4All Adjustable Cast Iron Dumbbells: traditional adjustable dumbbells that use a bar, weight plates, and threaded collars to hold everything together. They do, however, take forever to adjust, since you must remove the collars, load or remove plates, and rescrew the collars, all while doing weight-plate math. The fastest we managed a weight change for one dumbbell was about 25 seconds; this means you’re looking at about a minute of rest between exercises, and you have to resist the very strong temptation to just do your next move using the same amount of weight, which could mean either not enough challenge or a serious struggle.
Another quirk is that these bars and the corresponding holes on the weight plates measure 1.15 inches in diameter, making them incompatible with a more-standard 1-inch bar and plates, so you can’t increase the load by using plates from another set.

Weight Vest Weights for Hyper Vest » Hyperwear
com” allow=”autoplay; encrypted-media” allowfullscreen=”allowfullscreen”/>
Innovation starts with the fundamentals. Hyperwear created the smallest adjustable weight vest weights for the Hyper Vest® PRO and ELITE performance adjustable weight vests. Zinc-plated galvanized steel is used for density and rust resistance. The small size keeps the Hyper Vest comfortably against your body for top performance and thin fit. For the FIT and the TAC adjustable flexible plates, Hyperwear invented 1/2 pound containers that are Made in the USA from 100% recycled steel shot. Choose the correct weights for your model:
- PRO and ELITE: Booster boxes with 5 lbs of individual weights can be installed using the included tool or by hand by simply using a finger to open the individual weight pockets and sliding the weight in place. Fold the elasticated pocket flap back in place to ensure weight is held in place. Pockets in the Hyper Vest PRO and ELITE can hold two. Maximum capacity is based on the number of pockets and depends on the size of your vest.
- FIT: individual weights are 1/2 pound and one fits per pocket. If you buy a 5 lb vest you will have 10 empty pockets available to load to the 10 lb maximum capacity.
- Hyperwear TACTICAL Flexible Plates: are offered in pairs of 6 lbs and 9 lbs trapezoidal shape plates. You can full adjust the weight of the plate by removing and adding 1/2 lb individual weights that are included.

How to choose a badminton racket?
Tips for choosing a good badminton racket
This guide answers the question “How to choose a badminton racket”. The guide will be useful to both beginners and experienced badminton players, as well as to all those who choose a badminton racket as a gift.
The Guide also provides advice to parents of young badminton players on choosing a badminton racket.
In order to choose the right racket for playing badminton, you need to know what the racket itself consists of and what characteristics of the racket affect the quality of the game.
Construction of badminton racket
and its most important features
Badminton racket consists of:
- 1. Rim head;
- 2. Tee;
- 3. Rod;
- 4. Cap
- 5. Handle.
Racquet main features:
- • Weight
- • Handle size
- • Balance
- • Stem stiffness
- • Racquet material
Badminton racket weight
Badminton rackets weigh between 54 and 94 grams. The weight of a badminton racket is indicated by the Latin letter “U” and a number.
The marking is usually indicated on the cap. As you can see from the table, the lower the number, the heavier the racket, for example, a 3U racket is heavier than a 4U racket.
| Racket weight marking | Racquet weight in grams |
|---|---|
| 2U | 90-94 |
| 3U | 85-89 |
| 4U | 80-84 |
| 5U | 75-79 |
| 6U | 70-74 |
| 7U | 67-69 |
| 8U | 62-68 |
| 9U | 58-61 |
| 10U | 54-57 |
At the time of writing, the lightest racquet in the world Kumpoo Power Control Nano 10U (model 2019years) weighs 54 grams.
Racket selection
How do you know what weight racket is right for you?
We recommend following these guidelines:
- A heavier badminton racket will give you more power, while a lighter one will give you more maneuverability.
- A feature of heavy badminton rackets is that it is more difficult to make technically accurate strikes with them. Also, a heavy racket can cause fatigue in the hand during prolonged intense play.
- There are training racquets weighing over 100 grams. These badminton rackets are designed to train the muscles of the wrist and forearm.
Badminton racket handle size
Racquets differ not only in weight, but also in the size of the handle. The size of the handle of a badminton racket is indicated by the Latin letter “G” and a number.
There are 6 racket sizes: G1 – G6. The smaller the number, the larger the handle.
The handle size is usually indicated on the racket cap in combination with the weight of the racket, eg 3UG4.
Most racquets are available in G4 and G5 handle sizes.
If you don’t know what size badminton handle you need, we recommend purchasing a racquet with a thinner handle, as you can always add extra grip to increase the size.
The racquet grip is also used to provide a better grip on the racquet. Often, when buying a new racket, the flu is immediately wound.
Badminton racquet balance
The balance of the racquet, or the balance of the racquet, is determined by the distribution of the mass of the racquet between its head and handle. Depending on the balance, there are three categories of badminton rackets.
Head-Heavy Badminton Rackets:
Head-Heavy Badminton Rackets are designed for players who prefer an attacking style of play.
This racket has its center of gravity shifted towards the rim of the racket, which contributes to an increase in the force of impacts and a greater attack efficiency.
At the same time, with a racket balanced to the head, it is more difficult to play defense due to less control of maneuverability and it is more difficult to make a quick exchange of blows.
If you are an experienced player with good technique and prefer an attacking style, we recommend you to purchase a Head-Heavy badminton racquet.
Even-Balance Badminton Rackets:
Even-Balance Badminton Rackets are a versatile tool for playing a variety of games.
Racquet neutral balance, i.e. the even distribution of its mass between the head and the handle provides the badminton player with a combination of high punching power, optimal maneuverability and accuracy.
If you play both doubles and singles, practice both attacking and defensive playing styles, we advise you to purchase an Even-Balance badminton racquet.
Head-Light Badminton Rackets:
Head-Light Badminton Rackets are primarily designed for athletes who primarily play doubles and/or prefer a defensive style of play.
The Head-Light badminton racquet has its center of gravity shifted towards the handle, so it is much easier to maneuver with such a racquet when exchanging blows quickly. This is very important when playing defense and playing on the net.
At the same time, in order to carry out a powerful head-light attack with a badminton racket, a player must have excellent technique, because. it is more difficult to provide a strong blow with such a racket than with a racket balanced to the head.
Racket balance tips:
- To increase the balance in the head, you can stick adhesive tape on the head of the racket;
- To make the racket more balanced to the handle, wrap extra tape around the handle.
Badminton racquet shank stiffness
Badminton racquet shank stiffness determines the degree of control of the racket during play. Badminton racquet manufacturers sell four racquet stiffnesses:
Highly flexible
Very flexible
Flexible
Flexible
Medium
Medium
Stiff
Rigid
When choosing a racket, you should rely on the physical strength of your wrist and your sports experience and level of training.
Rigid racquet has more energy potential, more control and power, but only players with a fast and strong hand can unleash it. If the athlete’s hand physical characteristics, playing experience, and training level are more of a beginner or intermediate level, a hard and very hard racket will be less effective at hitting hard.
A flexible racquet is less technically and physically demanding, but will generate less power on impact, reducing control.
- Flexible racquet perfect for beginner badminton players.
- For experienced athletes with good technique, a hard racket is a better choice.
- If you don’t know what firmness to buy, we recommend choosing a medium firm racket.
Badminton racket material
The earliest rackets were made of wood. (By the way, badminton appeared in the 19th century in England on the basis of the ancient Indian game “Pune”).
In the 21st century, badminton rackets are made using high-tech processes and materials to provide the variety of performance combinations required for effective play.
Materials and alloys used to make badminton rackets:
- iron;
- aluminum;
- aluminum graphite alloy;
- graphite.
If you are planning to play all the time or are purchasing a racket for a badminton player who trains on a regular basis, we recommend that you only purchase rackets made from graphite, because other materials have certain disadvantages. For example, metal racquets easily deform the rim (string tension or impact), and the racquet may need to be replaced quickly.
Therefore, even if you are a beginner and you are buying your first badminton racquet (or planning to get a racquet as a gift), we recommend purchasing a graphite racquet as the most reliable and durable option.
In our online store you can choose a graphite racket for both beginner and high-level players in the price range that is acceptable to you.
If you are buying a racket for occasional, infrequent outdoor games, rackets made from other materials will be a good option for you. Most likely, you will not feel a big difference in quality, but you can save money.
How to choose a badminton racket for a child
Badminton is a sport that allows you to develop not only physical fitness, health, but also analytical skills, the ability to work in a team. Therefore, if your child begins to train playing badminton, this is excellent and beneficial for his health and development.
How to choose a badminton racket for a child? There are shortened rackets for small children or small children (5 – 10 years old). If a child lowers a standard racket and it does not touch the floor in length, he needs a full-fledged racket.
Pay attention to the weight of the racquet and choose light models to avoid unnecessary physical fatigue and excessive stress on the joints of the young athlete.
