Our Top Pick
Bowflex SelectTech Adjustable Dumbbells
5.0

The Bowflex SelectTech 552 adjustable dumbbells are best suited for individuals who are looking for a space-saving solution for their home gym and value the convenience of easily adjustable weights.

Weight Range: 5 to 52.5 pounds (adjustable in 2.5-pound increments up to the first 25 pounds)
See latest price

The Bowflex SelectTech 552 Adjustable Dumbbells are the holy grail of home fitness equipment. These bad boys were like rare treasures during the peak of the pandemic, and after finally getting my hands on a set, we understood why they had everyone buzzing. 

The Bowflex dumbbells boast a sleek black and red design, making them the envy of any weightlifting fashionista. Constructed from a mix of steel, nylon, ABS plastic, and thermoplastic rubber, they not only look the part but also pack a punch. With the ability to replace a whopping 15 sets of traditional weights, they offer an impressive range of weights from 5 to 52.5 pounds

They also feature a unique dial system consisting of two dials – one on each side of the dumbbell. The weights change seamlessly without any snagging or finicky adjustments. Furthermore, another feature that deserves a special shout-out is the rubber grip on the steel handle. It’s like a cozy little cushion for your palms, allowing for comfortable, marathon sessions of lifting. Every purchase includes a year-long JRNY membership, meaning access to on-demand strength classes. 

However, these dumbbells can be a bit on the bulky side. And this bulkiness, while manageable for most exercises, can prove a bit bothersome for certain movements. And let’s not forget the quirky dial situation – turning it in two different places to change the weight can be a tad perplexing.

Finally, it’s worth noting that this pair of adjustable dumbbells max out at 52.5 pounds. So, if you’re a seasoned lifter seeking to conquer Herculean feats of strength, you might find yourself yearning for a bit more.

Cons

  • The bulky design may feel slightly cumbersome during certain exercises, such as deadlifts or overhead presses.
  • The dial system requires turning the dial in two different places to change the weight, which some users may find less intuitive.
  • The maximum weight limit of 52.5 pounds may not be sufficient for advanced or heavy lifters who require heavier weights.

NordicTrack Select-a-Weight Dumbbell Pair
4.0

The NordicTrack Select-A-Weight Dumbbells are best suited for individuals who value the familiarity of a traditional dumbbell design and prioritize affordability in their adjustable dumbbell choice.

Weight Range: Varied weights of 25-pound or 55-pound sets
See latest price

The NordicTrack Select-A-Weight dumbbells are the heavyweight champion of adjustable dumbbells. They offer a traditional dumbbell feel, boast a higher max weight capacity, and deliver an exquisite anti-slip grip. Who said you have to break the bank to get your hands on high-quality gear?

Their knurled handle is a delightful surprise in a set that’s priced around $350. It’s like having a touch of luxury in your sweaty palm. Unlike the smooth adjustment mechanism of the Bowflex, the NordicTrack dumbbells require you to slide weight pin selectors to choose your desired resistance for exercises. While it’s still a relatively quick process, HIIT enthusiasts might find it a tad slower for their fast-paced workouts. But hey, we can’t have it all, can we?

The NordicTrack Select-A-Weight sets of weights don’t have any awkward variations or cumbersome shapes, they are just great quality traditional, regular dumbbells. Plus, they have more metal than other budget-friendly adjustable dumbbells, so they’re built to withstand your toughest weight training sessions. 

When it comes to the range of weights, you have a choice between 25 and 55 pounds. Now, here’s a pro tip: go big or go home. Both options cost the same, so why not get the 55 lbs max weight and unlock the full potential of these mighty warriors? More weight equals more gains.

All in all the NordicTrack Select-A-Weight Dumbbells offer a killer combination of affordability, traditional dumbbell feels, and a comfortable grip. Sure, the adjustment mechanism might not be as smooth as their competitors, but that’s a small price to pay for the overall value they bring to the table.

Pros

  • Built with a traditional dumbbell shape and knurled handle, providing a familiar and comfortable grip during workouts.
  • Offers a high-value option with a lower price point compared to some other adjustable dumbbells on the market.
  • The weight selection mechanism allows for quick adjustments by sliding weight pin selectors, making it convenient for most users.

A Guide to Buying Adjustable Dumbbells: Factors to Consider for Effective Strength Training

Adjustable dumbbells have revolutionized home and commercial gyms by providing the flexibility of multiple weights in single compact dumbbell sets. These versatile fitness tools usually have a wide weight range and enable you to perform a plethora of exercises and customize your workouts according to your strength and fitness goals.

However, with so many options available on the market, it’s crucial to consider various factors before investing in adjustable dumbbells.

Weight Range and Increments

The weight range determines the minimum weight and maximum load each dumbbell can accommodate. Assess your current strength level and long-term goals to choose a weight range that will challenge you without limiting your progress.

Additionally, pay attention to the increments in which the weights can be adjusted. Smaller increments provide more precise weight adjustments, allowing for gradual progression. Conversely, larger increments may be suitable for quick changes during circuit-style workouts. Assess the weight range and increment of weights to ensure they align with your training needs and preferences.

Adjustability Mechanism

Evaluate the adjustability mechanism of the dumbbells to ensure they are easy to use and reliable. Different adjustable dumbbells employ various mechanisms such as traditional spin locks, selector pins, or dial systems. Spin locks involve manually adding or removing weight plates and securing them with threaded collars.

Selector pins and dial systems, on the other hand, allow for effortless weight adjustments with a simple sliding or turning motion. Consider the convenience, speed, and stability of the adjustability mechanism to ensure it suits your training style and preferences.

Build Quality and Durability

Look for sets of dumbbells constructed from high-quality materials like solid metal or steel, as they offer sturdiness and longevity. Pay attention to the locking mechanisms and ensure they are robust and secure to prevent any weights from slipping or becoming loose during exercises.

Additionally, examine the quality of the handles and any connecting parts to ensure they can withstand regular use and resist wear and tear. Research customer reviews and testimonials to gain insights into the durability and reliability of different brands and models.

Handle Design and Grip Comfort

The design and comfort of the dumbbell handle significantly impact your overall workout experience. Look for handles that provide a comfortable grip and ergonomic design. The handles should be textured or have a knurled pattern to enhance grip security and prevent slippage during sweaty workouts. Evaluate the thickness of the handles to ensure they are suitable for your hand size and allow for a natural and comfortable grip.

Additionally, consider the overall length of the handles, as longer handles can accommodate two-handed exercises. Opt for handles that promote proper wrist alignment and reduce the risk of strain or discomfort.

Space and Storage

  • Save

Consider the training space available in your home and the storage options for the adjustable dumbbells. Adjustable dumbbells come in various sizes, and some models have a compact design that requires minimal storage space. Evaluate whether you have sufficient room to store the dumbbells when not in use, such as in a designated rack or storage stand.

Additionally, check if the dumbbells come with any storage accessories, such as a compact tray or stand, to keep the weights organized and easily accessible.

Warranty and Customer Support

When purchasing adjustable dumbbells, review the warranty provided by the manufacturer. A warranty demonstrates the brand’s confidence in the product’s quality and offers peace of mind in case of any defects or issues. Additionally, assess the customer support provided by the manufacturer to ensure prompt assistance and satisfactory resolution if you encounter any problems with the dumbbells. Research customer reviews and testimonials to gauge the company’s responsiveness and reliability in addressing customer concerns.

All in all, choosing the right adjustable dumbbells involves considering factors such as weight range and increments, adjustability mechanism, build quality and durability, handle design and grip comfort, space, and storage requirements, as well as warranty and customer support. By carefully evaluating these aspects, you can select adjustable dumbbells that align with your strength training goals, provide versatility, and offer durability for long-term use. Invest in high-quality adjustable dumbbells to elevate your home or commercial gym setup and enjoy efficient and effective strength training workouts.

Frequently Asked Questions:

Are adjustable dumbbells worth it?

Adjustable dumbbells are indeed worth considering for anyone looking to create a versatile and space-efficient home gym. They provide a wide range of weight options in a single piece of equipment, saving you from purchasing multiple sets of fixed-weight dumbbells. This not only saves space but also makes it easier to scale your workouts up or down, depending on your fitness goals and progress.

Can you build muscle with 50 lbs dumbbells?

Absolutely, you can build muscle with 50 lbs dumbbells. The key to muscle building is progressive overload, which means consistently increasing the demands on your musculoskeletal system. Thus, 50 lbs dumbbells can be quite effective for growth, especially if you’re incorporating exercises that target different muscle groups and are progressively challenging yourself with increased weight or reps over time.

How safe are adjustable dumbbells?

Adjustable dumbbells are safe when used correctly and with proper form. They are designed with locking mechanisms to ensure that the weight plates do not slip or fall off during use. It’s important to ensure that these mechanisms are securely fastened before starting your workout. As with any weightlifting equipment, following the manufacturer’s instructions and using the dumbbells within their intended weight limits is crucial for safety.

Are adjustable dumbbells better than normal dumbbells?

Whether adjustable dumbbells are better than normal (fixed-weight) dumbbells depends on your specific needs and workout environment. Adjustable dumbbells are more space-efficient and cost-effective, as they replace multiple sets of fixed dumbbells. They allow for quick weight changes between exercises, making them ideal for varied and dynamic workouts. However, some users prefer the convenience of grabbing a set of fixed-weight dumbbells without having to adjust weights. Fixed-weight dumbbells can also be more durable since they have fewer moving parts. Ultimately, the choice between adjustable and normal dumbbells should be based on personal preference, workout style, space, and budget.
