Sit on the floor, back straight, shoulders down, abs engaged, soles of the feet together in front of you, and knees bent to the sides.
Pull your heels towards you while simultaneously relaxing your knees towards the floor.
Breathe deeply and hold for 10-30 seconds.
Stretch to the point of "mild discomfort," not to the point of pain. Never bounce. Do not push your thighs down to the floor with your hands.
Muscles Stretched: Inner thighs, hips
