Your hip flexors are located on your upper thighs just below your hipbones. These muscles allow you to bend at the waist and to lift your knees. Stretching your hip flexors prevents both hip and lower back pain.
From a kneeling position, bring the left foot forward making sure that the left knee is over the ankle and the hip is bent about 90 degrees. Place both hands gently on the left thigh to help maintain a straight, tall spine.
Pull your shoulders blades down and back. Engage your abs to brace your spine. Keep your pelvis stable. (Do not allow one side to shift higher or lower than the other side). Lean forward into your left hip while keeping your right knee pressed into the ground.
Hold the stretch position. Complete on one side before alternating to the other hip.
