Adjustable Dumbbell - Black

As a fitness enthusiast with limited space at home, the POWERBLOCK Adjustable Dumbbells have been an absolute game-changer for my workout routine. These innovative dumbbells offer the versatility and convenience I've always wanted, allowing me to perform a wide range of exercises without the need for a full rack of traditional dumbbells. The first thing that impressed me was the compact design of the POWERBLOCK Adjustable Dumbbells. With their unique selector pin system, I can easily adjust the weight in increments, making it quick and hassle-free to switch between different resistance levels. This feature is perfect for superset workouts or when targeting different muscle groups during a single session. The build quality of these dumbbells is outstanding. The solid construction and durable materials give me confidence that they will withstand even the most intense workouts. The weight plates are securely locked in place with no rattling or movement, providing a stable and safe lifting experience. The weight range options are excellent, allowing me to choose from a wide range of weight settings that suit my current fitness level and goals. From light exercises for toning to heavy lifts for strength training, these dumbbells have got me covered. Plus, the weight range is expandable with additional kits, giving me room to progress and challenge myself as I get stronger. The grip of the dumbbells is comfortable and non-slip, ensuring a firm hold during exercises. The contoured handles feel natural in my hands, reducing fatigue and strain during longer workout sessions. Another significant advantage of the POWERBLOCK Adjustable Dumbbells is the space-saving design. They take up minimal space compared to a full set of traditional dumbbells, making them ideal for small apartments or home gyms with limited storage. I appreciate the clear and easy-to-read weight labels on the dumbbells, which help me quickly identify the desired weight setting. The color-coded system makes it effortless to select the correct weight, even in the middle of a fast-paced workout. Overall, the POWERBLOCK Adjustable Dumbbells have revolutionized my home workouts. They offer the convenience of having multiple dumbbells in one compact package, saving space and time without compromising on performance. If you're looking for a versatile and high-quality set of adjustable dumbbells, I highly recommend giving these a try. They have become an essential part of my fitness journey, and I couldn't be happier with my purchase.

I purchased this powerblock set primarily because of the cost savings over individual dumbbells and also the space savings. Let me say I’m glad I did, because after a couple months of use they haven’t disappointed in performance. I do have a couple of mentionable flaws that should be noted. To start, I ordered these and the available expansion packs. They did come in separate boxes as other reviewers noted, but all packages arrived on the same day. I took the liberty of contacting Amazon beforehand and informed them of the issues other buyers had (only receiving one single powerblock, for example). I requested they confirm there would actually be two powerblocks shipped with two tracking numbers. Amazon assured me both items would be shipped. Better yet, when they arrived on my doorstep, Amazon sent me an email containing a photo of both boxes on my front porch. Very pleased with their efforts in this respect. On arrival, the boxes for the powerblocks were pretty thrashed but still intact. This is due the weight of the blocks likely coupled with rough handling, but there is dense styrofoam surrounding the blocks so they were totally protected. I ordered the folding stand to go with the powerblocks as well. A stand at an appropriate height is is important for powerblocks IMO because it makes useability so much easier. Switching between weight is easy, just pull the plastic “U” pin and place at the desired weight. The plastic pin is durable enough but I do notice it’s flexible enough that it can be inserted crocked if not paying attention. Fortunately the plastic pin quickly retains its original shape it you insert it correctly. Also, ensuring the blocks are on very stable support is critical because the pin will not lock in place appropriately if the blocks are on a soft surface (a weight bench definitely is too soft, and even my rubber gym flooring is too soft). Another reason a stand is really convenient. Switching between 2.5 and 5lb increments is really easy by flipping the lever on the base of then kick and removing the weight inserts. There is a protective red rubber nub and goes on top of each lever, and they will annoyingly come off when you flip the lever over. For now I will hunt them down and put them back on, but I feel like over time I’ll get lazy and just leave them off. The finish in the metal at the end of the lever is kind of rough, and you could potentially scrape your hand on it, so I see why they put the protective rubber nub on. Maybe a tighter fitting nub would fix this issue. The grip on the powerblocks is awesome. I love the tapered shape, and the material provides excellent retention in the hand. Some users mention their knuckles contact the inside of the powerblock. Mine do too, however if you are thoughtful about your grip placement it actually feels like an asset; the powerblock actually feels like an extension of your limb on, say, shoulder presses and bicep curls. This feeling is different than traditional dumbbells and it does take a little getting used to, but I’ve grown to appreciate it. For reference on my hand size I’m a 5’11 adult male, I can almost palm a basketball but not quite. This is pretty average so if you have hands on the larger size then your knuckles will contact the inside of the powerblock that much more. The ability to change between 2.5lb and 5lb increments is a great feature. It allows me to get that much more out of my workout by keeping the volume high. I’d never pay for individual dumbbells, especially theses in between increments, and jumping up in 10lb increments often means sacrificing in terms of the number of reps. The ability to go up in smaller increments has translated into better gains. When taking out the weight inserts I keep my hand over one of the inserts while allowing the other to slide out. You can let both inserts out at the same time but trapping them in your hand simultaneously can be awkward. The folding stand I purchase has 4 small slots that I assumed were designed to hold each weight insert when not in use, another valuable aspect of the stand. The paint on the powerblocks has proven durable so far. When setting the blocks back down into the weights, the sides contact and shear past each other however the paint is durable enough to hold up to this. I do not drop the powerblocks under any circumstances, so the paint hasn’t been tested in that respect. As a side note: the owners manual states you can actually drop them if within a specified height and not void the warranty. Expanding on the cosmetic durability of these powerblocks, there are sticker labels on the blocks that have numbers and add to the cosmetic appeal of the product. On one of my blocks the stickers arrived with the stickers already peeling off. It also has bubbles underneath so that when you go to press down on the label it makes a “crackling” sound but won’t stick because the adhesive is lacking. I usually could care less about something like this, but the stickers actually help serve as a visual cue for which way the blocks are oriented and how they should be placed back into the stack. And with the sticker price these powerblocks command, the damn stickers should stay put. Pun intended. When in use, the powerblocks feel solid, even with heavier weights. There is a noticeable “clicking” that can be heard due to the weights shifting slightly during used. This doesn’t really bother me because I wear headphones working out and I am confident in the security of the “U” shaped pin. If you are closely playing attention you can feel the weights rattling a little, but the powerblock always feels like a solid unit. I also like how broad and flat the sides of the powerblocks are because it makes it comfortable to use your legs to raise the weights as you lean back for, say, chest presses. It also makes it a lot more comfortable to rest the blocks on your legs between sets. In all I am extremely pleased with this purchase, and I saved a ton of money and space over traditional dumbbells. I wish powerblock made extensions for this model beyond 90lbs because I’d be a buyer.

Se rayan con facilidad pero por el precio que tienen vale la pena.

Bueno primero me gustaría comentar respecto al tiempo de entrega que fué antes de lo esperado. Y siguiendo con lo más importante en relación al producto; la calidad del material es muy buena, tiene partes de plástico pero que muestra buena durabilidad y resistencia para hacer los ejercicios con plena seguridad, el agarre que se tiene me gustó mucho, de ninguna manera estorba al introducir la mano para hacer los movimientos en los ejercicios, la facilidad y rapidez para ejecutar los cambios en las pesas me pareció increíble, el dispositivo con la que se usa para establecer el peso deseado es de plástico, sin embargo el mecanismo que ofrece brinda total seguridad que al hacer el ejercicio no se salga y no pueda causarnos accidentes con el, el diseño sin duda me agradó, el espacio que ocupa es mínimo. Sin duda y sin arrpentimiento de haber comprado este producto, más que satisfecho. Y por último, leí con anterioridad en relación a la entrega de una mancuerna y no el par...por lo que me mantenía en duda para comprarlo por un rato, debo aclarar que recibí el set de 2 mancuernas, 1 mancuerna por caja, con manuales.

They do fit Sport 9.0 BUT you CANNOT use these with the Sport 9.0 kit 3. I repeat, this stage 2 DOES NOT fit Sport 9.0 kit 3. I will buy a kit 3 of this model however and everything should fit perfectly. If it doesn't, I'll edit my review but these are perfect so far!

Tengo algo ya de equipo, estas mancuernas que se pueden ir comprando de acuerdo a lo que vayas creciendo! De las mejores inversiones!

Justo lo que necesitaba para incrementar el peso de mis mancuernas Powerblock Exp 1 de 50 a 70 lbs. Ajusta perfectamente, tal como se espera.
