Instructions:

1. Stand or sit upright with your feet shoulder-width apart.
2. Extend one arm overhead, bending at the elbow so that your hand reaches towards the opposite shoulder blade.
3. With your other hand, gently pull the elbow of the extended arm towards the opposite side of your head, feeling a stretch in your triceps.
4. Hold the stretch for 15-30 seconds, then release.
5. Repeat on the other side.
