  • 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

  • Awesome DBs: Solid, Clean, Quick to Use
Style: Pair Size: 55 lb - Chrome Handle
These things are awesome, make drop sets way faster than before. Take up very little space. Very comfortable handles. Well made. My new favorite dumbbells alongside my power blocks.

  • For the price/quality ratio—you want this set.
Style: Pair Size: 55 lb - Copper Handle
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. ... show more

  • Good Adjustable Dumbbells for the Price Point
Style: Pair Size: 55 lb - Chrome Handle
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. ... show more

  • Nice weights
Style: Pair 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 ... show more

  • Well made 10-55lbs adjustable dumbbells
Style: Pair Size: 55 lb - Copper Handle
*** 4 month update - Sold them about a week or two after my last update. They cleaned up nicely for my buyer. They're overkill for the way I train. If you're doing strength based training like the Starting Strength approach, you'll find yourself taking 5 seconds to change the weight, then resting the next 4minutes and 55 seconds for your next set. Would buy again if I ever need something that changes that quick. *** *** 3 Month Update - Minor scuffs from use, they go back to looking like new with a quick wipe. Nothing has broken and am comfortable with the way the weights are held by the mechanism for both Dummbell Rows and Overhead Presses. I haven't dropped them or put my body weight on them (Pushups/ManMakers). You want to slide the handle in from the side a bit for a smoother insert. Overall I'm changing my rating from 4 to 5 stars. I'm convinced these are the new standard to beat when it comes to this weight range and price.*** Safety. The handles and components that allow it to work seem robust enough. It's plastic but definitely not the cheap kind. I was concerned about reviews saying the 5-25 handles would drop plates. I have yet to experience anything like that with these 10-55 handles. Save money, check. A set of 10-55lbs fixed cast iron dumbbells will run you approximately $650 on fbm at $1/lbs. Change weights quickly between sets, check. It's not a solid solid click, but it's a solid click. Extremely satisfied with this. They're just a bit finicky when aligning the handle back on the tray. Wether there's some weight in the tray or not. I think I'll dedicate two different areas for them. One for changing weight and the other for setting down between sets. This is where I think it's lacking. Size is manageable. There will be some exercises where you will need to adapt to the length of the handles. Durability. Survived first, day so far so good. I'll update if and when they fail me. *** 3 months of use and still going strong*** ... show more

  • Easy, fast, and smooth weight selection.
Style: Pair Size: 55 lb - Honeycomb Chrome and Black Handle
***** 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
