This exercise can be done almost anywhere - all that is needed is a small length of an exercise band or a pre-made exercise loop.
- Hold the exercise loop behind your head with one hand. With the other hand, grasp the loop behind your back.
- Exhale and straighten the arm that is over your head, pushing your hand toward the ceiling. Inhale and slowly return to the start position.
Repeat 8-12 times, rest, then switch arms.
