1. Lie on your back with your knees bent and your feet flat on the floor. You can put a small pillow under your head and neck if it is more comfortable.

3. Keep your lower back pressed to the floor. Hold the stretch for at least 15 to 30 seconds.

5. Repeat 2 to 4 times with each leg.

To get more stretch, put your other leg flat on the floor while pulling your knee to your chest.
