In a seated position, open your legs as wide as needed to feel a stretch in your inner thighs. If you're really tight, try sitting on a pillow to decrease the stretch, or try doing this stretch one leg at a time.
To increase the stretch, walk your hands forward while keeping your back straight, hinging forward from your hips. Hold this position for 20 to 30 seconds.
Then round your back, bringing your head toward the floor; hold this position for 20 to 30 seconds.
