This is a simple shoulder exercise.
- Stand on an exercise band with each end of the band in your hands. Keep your back straight and your knees slightly bent. Start with your hands beside your hips.
- Slowly move one hand forward and one hand backward. Make sure that you don't twist your torso at all. Also avoid shrugging your shoulders.
- Bring your hands back to the starting position, then keep going until the opposite hand is forward and the other hand is back. This completes one repetition.
Repeat 8 - 10 times, rest, then repeat the exercise sequence as desired.
