How to perform a One Legged Squat:
Stand with your feet approximately shoulder width apart and your hands on your hips or extended out in front of you.
Lift your non-squatting leg up, bending it at the knee slightly.
Begin to bend your squatting leg down towards the ground, keeping the right leg completely off the floor. Keep the weight of your body on your heel.
Continue to lower your body until your thighs are parallel to the floor.
Straighten your left leg to push yourself back up to position 2.
