Sit up straight with your legs bent and feet flat on the floor.
Slowly straighten your affected leg, pulling your toes up towards you.
Stop when you begin to feel a stretch down the back of your leg.
Keeping your back straight, lower your foot back down to the floor while simultaneously dropping your head downwards, chin to chest.
Straighten your leg out again while simultaneously lifting your head and tilting it backwards.
Lower your foot and drop your head forwards.
Continue this sequence at a steady speed.
