HOW: Get set-up standing, feet shoulder width apart, with the side you want to stretch - place the foot slightly in front of the other on an elevated surface. While maintaining a relatively flat back, neutral spine, and neutral foot position hinge at your hip and reach for your toes. Slowly come back to starting position and repeat.
FEEL: You should feel a stretch behind your thigh and knee. You may also feel a pulling sensation higher up on the back of your thigh of into your calf and foot if it is too intense you can point your foot down.
COMPENSATION: Do not bend/round your back too much as this will take away from the hamstring stretch.
