Hip External Rotator and Back Extensor Stretch
This is a seated-floor stretch that focuses on the glutes and parts of the lower back. With your legs laying flat on the floor, bend your left leg and place your left foot outside of your right knee. Take your right arm and anchor the elbow against the outside of the left knee. Place your left hand on the floor to help hold yourself up. Twist your trunk as far to the left while keeping the left knee stabilized with your right elbow. Keep in mind not to arch your back or bend from the waist. Repeat with the other side.
