Performing the: A Step-by-Step Tutorial Single Leg Squat
Lift one foot off the ground so you're balancing on one leg, keeping your lifted leg bent at the knee.
Slowly lower your body by bending at the hip and knee of your standing leg, as if sitting back into a chair, while keeping your chest lifted and back straight.
Lower yourself as far as you can, ideally until your thigh is parallel with the ground, while keeping your other foot off the ground.
Push through the heel of your standing leg to return to the starting position, keeping your lifted leg off the ground throughout the entire exercise. Repeat the exercise with the other leg.
