Benefits:
- Strengthens the targeted shoulder muscles.
- Supports shoulder stability and health.
- Helps balance the muscles around the shoulder.
- Joint friendly with light loads.

Additional Information:
The rotator cuff muscles are small, so use light weight and strict, slow reps. These movements support shoulder health rather than building size.
