Standing in front of a box, bench or another stable and elevated surface, rest one of your legs on the box bending your hip and knee at a #90º angle. From this position, push yourself up with a movement similar to going up a really high step. The movement ends with the leg which started the push being completely straight and the other in a #90º bend between knee and hip. Your upper body should be completely straight. From here, go back to the start position and change legs.
Count one repetition per lift.
– Stretch the body at the end of the lift.
– Control your descent.
