With your left hand, reach out and gently pull back on each finger, starting with your index. 15 Jan Make a fist with your hand, wrapping your thumb around your other fingers. Squeeze until you feel tightness, not pain. Hold for five seconds, breathing deeply. Release the fist, stretching your fingers outward, apart from each other. Hold the stretch for five seconds, breathing deeply. Repeat this exercise.
