How to perform the Cable Shoulder 90 degrees Internal Rotation

  1. Set up. Set up in a stable, balanced starting position appropriate for the Cable Shoulder 90 degrees Internal Rotation using your cable.

Coaching cues

  • Move with intent — every rep should feel deliberate, not rushed.
  • Drive force through your pectoralis major rather than momentum.
  • Keep your breathing steady: exhale on the hard part, inhale on the reset.

Common mistakes

  • Using too much weight and losing positional control.
  • Cutting the range of motion short and missing the target muscle.
