Loadable Dumbbells are an excellent alternative to expensive and space intensive sets of dumbbells.

Bells of Steel Loadable Dumbbells feature an aesthetic, rust-resistant black zinc finish and bright zinc on the sleeves. A 28mm handle gives you the feel you’re used to when using Olympic bars and the brass bushings allow for a smooth rotation.

  • Save thousands. Although a full set of Hex Dumbbells or Commercial Dumbbells can be a dream come true, the costs can quickly add up and that’s before buying a single dumbbell stand! By investing in just two Loadable Dumbbells, you’ll save thousands of dollars on gym equipment.
  • Save space. Full dumbbell sets have their place, but they can be tough to fit into a home gym. Even with our Residential Dumbbell Rack or Commercial Dumbbell Rack, you’ll be using up the most valuable resource in your gym — floor space. Au contraire, two Loadable Dumbbells can easily be stowed away in the corner without disturbing the natural flow of your gym.

Incredible Dumbbells

The quality of these dumbbells is top notch. I love the feel of the knurling, and the spin of the sleeves is effortless. I bought a pair for my wife, and their addition to our home gym has seriously upgraded our workouts. They're like high-quality miniature barbells, which means they feel sturdy and firm in the hand. I've done curls, rows, deadlifts, split squats, DB snatches, and even goblet squats (have to have some high-quality collars), and at every turn they've impressed me. UPS lost one of the dumbbells I ordered originally during the holidays, and BoS sent me a replacement dumbbell for FREE. Love the customer service, they've definitely made me a repeat customer. I recommend them to anyone looking for an alternative to fixed (and even most adjustable) dumbbells!


Bells of Steel

Thanks for the 5 Star Review Jonathan! Great to hear that you are enjoying your loadable dumbbells! I use these in my training as well and they are great for adding versatility without taking up too much money or space. I am glad you had a good experience with our customer service team as well! Happy lifting! Brandon and the B.o.S. Team

Loadable Dumbbells

I bought a pair of these dumbbells recently as a Christmas gift to add more variety to my training as mostly l train at home with straight bars and a Swiss bar. They are well made. The handles have a good texture. One of the best features are that the spindles spin. Great alternative to buying fixed dumbbells.

better alternative to “adjustable” dumbbells

I switched to the Bells of Steel Loadable Dumbbell from using Powerblock adjustable dumbbells. The Powerblock dumbbells only go up to 50 lbs, were warped in transit, and one of the plates is already broken due to a flimsy weld. The BoS Dumbbell is another animal entirely. I don’t have to worry about damaging it, I can load it over 50 lbs, I can easily wrap straps around the handle for high-rep marathon sets of rows, and I can use the same plates I already own for my olympic barbell. This loadable dumbbell is the most natural complement to a barbell setup on the market, imo.

Thanks for the 5 Star Review David! Great to hear that you are enjoying your new loadable dumbbells! They are a great option if you need to go extra heavy on dumbbell exercises, or want to save money and space! Happy lifting! Brandon and the B.o.S. Team

Great loadable option!

I had an older version of BoS loadable dumbbell so ordered a second to make it a pair. The design had been updated and the older version is a different length, so I ended up returning the dumbbell. That being said, the knurling was nice, the handle isn't too long, and the sleeves have plenty of space to load plates. Aside from minor finish blemishes, there's nothing to complain about!

Hey Anderson, Thank you for the review, We are sorry our update model didn't suit your needs. Yours in strength, William & the BoS crew
