This superset has two very challenging moves which will improve balance and coordination and which will blast your glutes. The first exercise is one-legged dumbbell deadlifts which can be performed with either one or two dumbbells (I prefer using two dumbbells). Holding dumbbells, you will bend at the waist while lifting one leg straight back and keeping your other leg straight but with a soft knee. The next move is one-legged cable kickbacks in which you will kick one leg straight behind you while squeezing the glute and keeping the rest of the body stationary.
