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.

I’m sure bowflex is a superior product, but i’m not gonna shell out $500 for any adjustable dumbbell. CAP is a brand you would find around my home gym so I already knew i was getting an 80% legit product. These aren’t clanky or cheap feeling. The adjuster works pretty smoothly. They have to rebalance a certain way in your hand (which is an odd sensation) but you get used to it. Solid buy for an intermediate lifter who doesn’t want to pack up his entire gym for every road trip.

Size: 55 lb - Honeycomb Chrome and Black Handle
These are nice they work well they lock in well. I wish these came with either a little elastic or Velcro to attach the base around the handle for transport. You absolutely have to have the base in order to change the weights. But when you pick the weights up they leave the base. So when you transport them you have to carry four things instead of just two. That being said they work the way they should they're comfortable. They feel a little unbalanced and they're a little awkwardly sized. But if you want one wait that's going to do it all it's going to have some issues. That being said I'm very happy with them. Or should I say my son, who stole them from me, is very happy with them

After doing a lot of research on adjustable dumbbells, I selected the CAP 55# adjustable dumbbells. The dumbbells were delivered in excellent condition upon ordering. The dumbbells are very large (depending upon how much weight is selected) compared to conventional dumbbells, so this takes some getting use to. Most exercises can be performed without any hindrance from the large size bar. The dumbbells are made in China, and have a 2 year warranty. One negative: both of my dumbbells have a small metal burr on the handle collar from manufacturing. The burr is sharp and causes discomfort when using the dumbbells with bare hands. I recommend wearing lifting gloves when in use. Overall, the dumbbells are good quality and a good value for the money.

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.

***** 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.

Thought I would give these some time before I reviewed them. They are well made. I have been using them consistently for 4 months now. They are not the kind of hex bells you can dump on the floor just because of the nature of how they are built. That said, if you have limited space like I do in my apartment and don't typically throw your dumbbells around anyway, these work great. The dial is really handy and you get an audible "click" when you make an adjustment. The numbers are clearly labeled on both sides of the unit. Grip is solid. They can be removed with no trouble and put back into the base with limited effort (Other than lining up the unit with the base which one could expect from an adjustable dumbbell). In ending money well spent. CAP has some really decent products that don't cost an arm and a leg.

Size: 55 lb - Black Handle
In Short: A really nice set of adjustable dumbbells. There are a few areas for improvement here and there, but this set can easily replace a full rack of weights for most workouts! The Longer Story: One of the downsides of getting older is that you have to take better care of your health, which means more rigorous exercise and a focus on strength. While browsing through Facebook Marketplace, I initially bought some single-weight dumbbells, but I soon realized that different exercises require different weights to train different muscle groups optimally. I am far from a pro athlete - I train about once a week - but it became painfully obvious that, for me, a 20lb weight was insufficient for a goblet squat, yet way too heavy for a lateral arm raise. Keeping a ton of cast iron lying around wasn't ideal, so I finally went the route of adjustable weights. These CAP dumbbells work well. They have an interesting mechanism where the weight can only be changed when the dumbbell is "docked" in its cradle. You simply rotate the center grip to adjust the weight in 5lb intervals (from 10lbs up to 55lbs), and the dumbbell symmetrically loads the plates on both sides. Unlike other adjustable sets, this allows you to set the weight with a single rapid movement. The only downside to this specific design is that you cannot load the sides unevenly for more obscure exercises (theoretically possible if you remove a plate from just one side, see the video). Another small downside are the not perfectly flat surfaces on the sides of the dumbbell - this makes laying them down "on the side" (vertically) a bit less stable and wobbly. The unit is very solidly built - not surprising considering the weight it has to carry. I would not necessarily toss it on the ground, but it feels reassuring enough to do overhead raises without fear of getting hit by loose weighs. As long as you are not doing any rapid-movement shenanigans with heavy weights, the loading mechanics should not be a concern. One specific feature I love is the hex shape; I use dumbbells for pushup variations, so having a set that doesn't roll away is a major plus. So, why not five stars? There are a few quirks. As you can see/hear in the video, you have to be quite delicate with the alignment of the grip inside the cradle. This can get annoying after an exhausting set where fine motor skills are fading; if you place them in a crooked fashion, the adjustment mechanism won't trigger (which is actually a great safety feature). Acoustically, you can hear the mechanism rattling a bit when you shake them, especially at lower weights. Finally, I personally would have preferred 2.5lb intervals for better fine-tuning of weights. Overall, these are minor gripes. This is a great set of adjustable dumbbells that saves a ton of space. It’s a perfect addition to my beginner workout routine, allowing me to easily experiment with different weights!
