The Better Body Rubber Hex Dumbbell Expansion Sets let you add heavier weights without replacing the dumbbells you already have. Each expansion matches our existing Rubber Hex Dumbbells in feel, finish, handle style, and 5 LB progression.
Already own 5–50 LB?
Already own 5–75 LB?
Every expansion includes each 5 LB increment in the selected range, giving you consistent progression with no missing weights. The 55–75 LB and 55–100 LB options include additional storage, while the 80–100 LB option is designed for lifters who already own the 5–75 LB setup.
Start with the weight range you need today and expand your set as your strength grows.
