Description

The CAP Rubber Coated Dumbbell Weight collection is designed to deliver the durability, performance, and versatility serious lifters expect from premium strength training equipment. Built for home gyms, garage gyms, personal training studios, schools, hotels, and commercial fitness facilities, these dumbbells combine advanced engineering, sustainable materials, and user- focused design to support every stage of your fitness journey. Manufactured with solid ASTM cast iron heads and durable recycled rubber coatings, these dumbbells provide outstanding durability while helping reduce workout noise and protect floors, equipment, and training spaces. The recycled rubber coating utilizes reclaimed materials that help reduce landfill waste while delivering excellent impact resistance, long-term wear protection, and a premium appearance. The collection includes both traditional Hex Head and premium 12-Sided Head designs. Hex heads help prevent rolling and provide secure storage between sets, while the 12-sided design combines anti-roll functionality with improved stability during floor-based exercises such as dumbbell push-ups, renegade rows, planks, and bear crawls. The 12-sided shape also allows smoother transitions and more even impact distribution during use. To support different training preferences, CAP offers multiple handle options across the collection. Chrome Handle models feature a polished finish that provides superior corrosion resistance, low maintenance, and a professional gym appearance. Black Oxide Handle models preserve crisp knurling for enhanced grip performance and improved chalk retention, making them ideal for lifters seeking maximum control. Comfort Grip Handle models feature an ergonomically contoured shape that helps reduce hand fatigue, improve comfort, and provide a more natural lifting experience during extended workouts. Every handle is manufactured from premium cold-rolled steel and precision-machined with medium knurling to deliver the ideal balance of grip security and comfort. The medium knurl pattern helps reduce slipping while maintaining comfort during presses, curls, rows, lunges, shoulder exercises, and full-body strength training routines. At the core of every dumbbell is advanced SonicWeld™ construction technology. This premium manufacturing process creates a molecular-level bond between the handle and dumbbell heads, helping prevent loosening, spinning heads, and common structural failures associated with traditional press-fit designs. The result is exceptional durability, precise balance, and long-term performance designed to withstand demanding training environments. Raised weight markings provide quick and easy identification during workouts, allowing for efficient weight selection and faster transitions between exercises. Available in multiple weight increments, singles, pairs, and complete sets, the CAP Coated Dumbbell Weight collection makes it easy to customize a training program that supports progressive overload, muscle growth, strength development, endurance training, conditioning, and functional fitness. Whether you're building your first home gym or outfitting a commercial training facility, CAP dumbbells deliver the premium materials, advanced construction, and trusted performance needed to help achieve your fitness goals.

  • Best value dumbells
Great value for standard dumbbells. They feel solid and well-made, and they’re perfect for basic home workouts. Nothing fancy, but they do exactly what you need at a good price. Would definitely recommend if you’re looking for a simple, affordable set.

  • It works if you use it
Great dumbbell. Not much to leave a review on. Nice grip, material seems like it will last awhile.

They do have a slight smell as others have mentioned but it doesn’t bother me.

  • Depends on the weight you get
The prices listed are for a single dumbbell, not a set. We ordered two 20 lb dumbbells to replace our all metal 20 lb weights (which were incorrectly weighted and imbalanced "20-pound weights"). Now no more noisy clanging the ends of the weights together when working out and no more banging hard metal on the floor. These weights are perfect. No grip, no clanging and banging, no smells, no flaws and we checked the weight on a scale...they are both EXACTLY twenty lbs! Neither one is a single ounce off. No more working out with imbalanced weights. These are high quality dumbbells. Because of the return policy we were at ease purchasing these online. If there were any problems an easy return would resolve it. You can't go wrong with that kind of assurance. The fact that we did not need to return them was (the hope and) the ideal outcome. Now that we know they are accurate and high quality we will be ordering the next weight up set, from CAP. Up to this point, EVERY CAP weightlifting item we have ordered on Amazon has been good value and quality, including these. Highly recommend these CAP dumbbells. Update: That information is still true for the 20 lb dumbells. We did end up ordering a pair of 25 lb dumbells shortly after the 20's. However, the product was not the same perfection of weight. Both of the "25 lb." dumbbells were .4 lbs. underweight, which was a bit disappointing. They are covered with the return option, but these are pretty heavy to have to return. We would have if returned the weights if each had not matched the other, though, so there is that. We won't be lifting QUITE 25 lbs. each side, but we WILL be lifting equally on both sides. Both of the "25's" weighed in almost half a lb. underweight, at exactly 24.6 lbs. Update: The 15s were both exactly 15. ... show more
