    • Easy and Effective Way for a Beginner in Their 50s
Style: Pair Size: 25 lb - Honeycomb Black Handle
I’m 50 and just getting back into a workout routine, and the CAP Barbell Adjustabell has been perfect for me. It’s incredibly easy to adjust weights—from lighter for warm-ups to heavier for strength training—and switching between exercises is smooth and fast thanks to the dial mechanism. The handle has a good grip, even with sweaty palms, and the compact design fits neatly in my home gym space, saving me the hassle of storing multiple dumbbells. I’ve been able to do a full range of moves, curls, presses, rows, even squats without feeling awkward. The adjustment process is intuitive and quick, so I stay focused on my form and reps. While these aren’t the most heavy-duty dumbbells out there, they’ve been solid for beginner-to-intermediate use. That extra convenience of not having a big set of weights cluttering up my space is worth it. Overall, if you’re starting or restarting your fitness journey later in life, this dumbbell is a fantastic tool. It’s reliable, easy to use, and great value for what it offers. ... show more

    • Great dumbbell, saves space, 5lb increments.
Style: Pair Size: 55 lb - Honeycomb Chrome and Black Handle
I use these 3 times a week and they are great. Sliding them on and off the holder is at times a bit difficult to align but slow and steady gets the job done. I can't imagine the other kinds don't have similar experience. These just work. Only thing I'd like is if they could go between the 5s, like 2.5 lb increments. But I knew that when I purchased great product. Grip is solid but may be a bit large for small hands. Weight adjustment is solid and I'm not worried they will fall out. I'm happy with these. ... show more

    • Easy, fast, and smooth weight selection.
Style: Pair Size: 55 lb - Honeycomb Chrome and Black Handle
Review Image by TG16Fanatic TG16Fanatic
***** Update: 6 months in with 3-5 workouts a week and these are still rockin' like day 1! ***** I couldn't find reviews for this set of dumbbells online anywhere prior to purchasing, but I took a chance on them because I like the CAP brand, they look quite nice, and the price is very good for this amount of weight. I'm happy to say that I'm glad I took a chance on these instead of some no-name brand! Pros: - The weight selections are sequential from low to high. Some of the no-name brands I was considering had seemingly random weight orders (i.e if you want to go up 5 lbs, rotate 1 clockwise, but for 10 lbs, rotate 2 counterclockwise... which would be confusing and annoying). - The handles, when the dumbbells are docked in their holder, rotate easily but feel solid and click into place for each weight increment. When not docked, there is minimal play and they remain locked into place quite securely. I never feel like I'm holding anything but a normal dumbbell. - Regardless of how many plates you have loaded onto the handles, the dumbbells line up and slide into their base with ease. I haven't had any failed attempts where I had to lift back up and try again. Just good engineering all around. - The handles are smooth while having a nice texture, paradoxically giving a pretty good grip while not tearing up your palms (though I wear gloves for higher weights just because). Cons: - Not really the product's fault, but all adjustable dumbbells tend to be a bit wider than standard dumbbells. I haven't found this to be a huge problem, I just take care not to let them hit each other side-on for fear of breaking them. Other: - I haven't had them long enough to comment on durability, but I will be sure to update the review if there are any problems. ... show more

    • Solid Set at a good price
Style: Pair Size: 55 lb - Honeycomb Chrome and Black Handle
These adjustable dumbbells are super convenient and save a ton of space. Switching weights is fast and easy. The only downside is that if you don’t pull straight up, the plates can catch a bit when lifting from the base. Not a dealbreaker, but something to be aware of. Overall, solid set for home workouts! ... show more

These barbells are solid and work great. The base doesn't seem overly strong but I put the barbells down gently and I don't think I will have a problem

    • Great set of weights
Style: Pair Size: 55 lb - Honeycomb Chrome and Black Handle
These are exactly what I needed. I spent some time looking at several different brands, including some name brands. I took a chance on this one and I'm glad I did. The handles are comfortable and easy to adjust. And I like that there are plenty of weight choices so it covers all my needs.

    • Plastic Parts make these unusable

Review Image by Vance A. Hays Vance A. Hays
DO NOT PURCHASE. The concept of these is great. I've had the 25-lb set for years and never had an issue. Once I moved up to these, at 55 lbs, the problems were endless. I bought my first set in September 2025. By the first of October, the cheap little plastic rings that actually manage the Select-a-Weight mechanism fell out in several pieces and the weights dropped off like confetti. I returned that set, thinking it was a one-off. My second set lasted until yesterday, January 28, 2026. And I think only because I took most of December 2025 off! The little cheapo plastic rings that actually control these things is ridiculously fragile, completely not up to the task of dealing with the stresses and torquing its subjected to during a workout. ... show more
