FEIERDUN’s adjustable dumbbell set swaps several pieces of gym gear for one kit: it works as a single dumbbell, a kettlebell, a barbell, and more. It suits home lifters at any level who want room to change weights as their training progresses.
By the numbers
- 6 lbs to 22.5 lbs range for the single dumbbell setup
- 4 lbs to 19.5 lbs range for the kettlebell setup
- 8 lbs to 45 lbs range for the barbell setup
- 15mm high-density foam pad over a 5mm steel core, sized 430 mm
Good to know: Coverage runs for 1095 days on every dumbbell, so the set is backed for about three years.
