A group of four shoulder muscles and tendons that help centre and control the upper-arm bone in the socket.
Why Rotator cuff matters
The rotator cuff supports shoulder movement and stability but cannot be made injury-proof with one drill.
A practical example
Light cable external rotation may be used as part of a wider shoulder-strength programme.
Common mistake
Loading rotation exercises too heavily or self-treating persistent shoulder pain without assessment.
Keep the context in mind.
Training and nutrition terms describe general principles. The right exercise, intensity or food target still depends on your experience, health, goals and schedule.
Personalised coaching
Apply the principle to your own training.
A definition is useful, but your programme still needs to match your experience, schedule, recovery and goals.
