Properly stretching hamstrings can reduce your risk of injury, decrease back pain issues and improve your posture.
— Starting Position. Lie on your back with your legs extended and your back straight.
— Keep your hips level and your lower back down on the floor.
— Bend your right knee toward your chest, keeping your left leg extended on the floor.
— Slowly straighten your right knee, grabbing the back of your leg with both hands. Pull your leg toward you gently while keeping both hips on the floor.
— Breathe deeply and hold for 10-30 seconds. Repeat on opposite side.
— Repeat 2 to 4 cycles
— Stretch to the point of "mild discomfort," not to the point of pain. Never bounce.
