Single knee-to-chest stretch

Lie on your back, bend your knees, and have your feet flat on the floor. Pull 1 knee toward your chest until you feel a stretch in your lower back and buttock area. Repeat with the other knee. If you have knee problems, pull your knee up by grabbing the back of your thigh instead of the front of your knee. You can also do this exercise by grabbing both knees at the same time.
