Step ups and raise back leg up-drive through foot that is on the step/bench pushing through your heel and glute. As you come to the top of the movement extend back leg up raising through glute. I prefer to do one side then the other as I feel it allows you to focus on your glutes more. Side step ups and raise leg out to side-start on the side of the step/bench with foot on bench. Pressing through glute/hamstring as you come up extend other leg out to side and if able slightly back to focus on glute more.
