Start standing with your feet hips-width apart, facing a wall. Place your right hand on the wall, keeping a slight bend in your right elbow. This is your starting position.
Rise up onto your toes, and bend your right knee to a 90-degree angle, lifting your right foot behind you.
Lower your left heel to the ground while keeping your right foot in the air.
Set your right foot on the ground to return to the starting position.
This counts as one rep. Complete 12 reps on each leg, then repeat for two sets.
