The Superset uses four Dualbell dumbbell converters so you can load two dumbbells per side—reaching weights a single pair of dumbbells cannot. Combine a 50 lb and 30 lb dumbbell for 80 lb per side, or mix other sizes to progress in smaller increments using the dumbbells you already own.
This four-adapter setup is designed for lifters who want room to keep adding weight. Want collars included? Choose the Dualbell Superset + Collars.
