One exercise effective at improving tone is the overhead shoulder raise. The overhead shoulder raise involves holding a medicine ball or other weight in front of your body and then simply raising it overhead.
|Front Shoulder Raise|
- Feet spread shoulder width apart, shoulders pulled down and back, abs pulled in
- Rotate the weight while keeping arms straight (not locked elbows)
- Do not shrug or sway. Always keep your body still
- You should feel this behind the shoulders and along the center of the back
