1 - Stand with your feet about shoulder-width apart and toes slightly turned out.
2 - Hinge at your hips and reach down to grab your toes, the front of your shoes, or your ankles while keeping your legs as straight as comfortable.
3 - Pull yourself gently down into a deep squat, keeping your chest lifted, elbows inside your knees, and heels on the ground if possible.
4 - Pause briefly in the bottom position and use your elbows to press your knees outward while maintaining a tall chest.
5 - Keeping your hands on your feet or ankles, raise your hips toward the ceiling and straighten your legs as much as comfortable to feel a stretch through the hamstrings.
6 - Return to the deep squat position and repeat for the desired number of repetitions.
