How to do it

  1. Stand tall and bring one arm straight across your body at chest height.
  2. Use your other hand to gently pull it closer into your chest.
  3. Ease into the stretch across the back of your shoulder.
  4. Hold and breathe, then switch arms.

The one cue that matters

Keep the shoulder down, don't shrug it up toward your ear.

Muscles worked

This simple pull-across targets the back of the shoulder, easing the rear delt and surrounding tissue that gets cranky from pressing volume and desk posture. Working one arm at a time lets you fine-tune the angle and pressure until the stretch lands exactly where you feel tight. It costs thirty seconds a side and pays back in smoother pressing and pulling.

FAQ

What does the cross-body arm stretch actually stretch?

The rear of your shoulder, the posterior delt and the tissue around it. It is the go-to for shoulders that feel tight after bench sessions or long days at a desk.

How hard should I pull my arm across?

Gently, to a clear stretch and never into pain. Ease in, breathe for 20 to 30 seconds and let the tissue give. Forcing it just makes the shoulder guard harder.

Why do I shrug during this stretch?

The trap sneaks up to protect the shoulder. Set the shoulder blade down first, then draw the arm across, and if it shrugs anyway, reduce the pull.
