Reach one foot behind you and rest the top of it on the bench. Stand tall, keep your chest up, and engage your core. Your front foot should be far enough forward so that your front knee stays over your ankle when you lower down. Slowly bend your front knee and lower your back knee toward the ground. Keep your weight in your front heel.Drive through your front heel to return to the starting position, keeping control of the movement .Complete all reps on one leg before switching to the other.
