HOW: Lay flat down on your back. Bring your leg to the side of your body and gently press your foot and knee down towards the bed next to your chest. You should feel a good stretch on the backside of your ass. Keep the tension for about 10 seconds before relaxing a changing legs. Stretch a couple of times on each side.
This little stretch exercise is good for when getting ready for bed and you need to stretch your bottom after a long day at work.
