HOW: Begin standing up with your hands against a wall with one knee up towards your chest. Drive the elevated leg down towards the floor then quickly exchange legs back to the starting position. This movement should be performed quickly and with power. Lean up against the wall for the entirety of this exercise.
FEEL: You will feel both legs working, particularly the calves, quadriceps, and hip flexors. However, the majority of the work will likely be in the leg you are standing on.
COMPENSATION: Focus on triple extension at the top of the motion, meaning standing on your toes with your heels off the ground, knee in extension, and hip in extension
