The one thing these dumbbells have over the modern adjustable ones is versatility. You can use the single plates off the dumbbell for various exercises and adjust the weights in different combinations.
With a maximum weight of 52.5 lbs, the Yes4All dumbbell comes with one 16” x 1.15” handle and bar, two collars, and 12 plates (8 x 5 lb, 2 x 2.5 lb, and 2 x 1.25 lb). The convenient, star-lock collars bear a rubber trim that prevents slippage and loosening of the plates.

2. Sunny Health & Fitness Chrome Dumbbell Set with Carry Case
- Chrome plated for a clean look
- Plates can be removed for versatility in excercises
- Only can order 33 lb dumbbell set
- Screw off nut to remove plates
If you want a completely chromed-out dumbbell set, then look no further than Sunny Health’s offering. This eye-catching set comes with two solid steel handlebars and four cogs. The plates consist of cast iron. And, everything shines the way that only chrome can.
The steel handlebar bears diamond-knurling for extra grip and slip-resistance during heavy workouts. And, the solid steel star-locks have rubber rings to help prevent slippage and loosening.
As a bonus, this set includes a free carry case for fitness buffs who constantly find themselves on the go.
Overall, the Sunny Health dumbbell set may represent the best value on this list, considering purchasers get two handlebars, four star-locks, and 12 plates (8 x 2.5 lb and 4 x 1.5lb). It serves as a great set for beginners, but we would have preferred a higher maximum weight per dumbbell so it would suit users of a higher skill level.
3. CAP Adjustable Dumbbell Set
- Get two 30 lb adjustable dumbbells for under $100
- Black cast iron weight plates
- Plates can be removed to assist with other exercises
- Budget friendly
- Bullet proof!

The CAP Adjustable Dumbbell Set provides that old-fashioned aesthetic and feel during a workout. The rugged cast-iron plates feature a durable, black epoxy coating to lengthen their lifespans, preventing rust and corrosion. And, the chrome-plated, cold-rolled steel handlebars have the same diamond-knurled grip that you encounter at the gym.
The steel star-lock collars bear a rubber O-ring to secure a tight fit and lessen the likelihood of slippage while working out.
There does, however, seem to be a discrepancy over the width of the handlebar. While CAP claims the handlebar measures 1” in diameter, it actually comes out to 1⅛”. Those willing to spend a little more can purchase up to a 100 lb pair!
