Setup
- Stand tall with your feet hip-width apart and your spine in a neutral position.
- Bend your elbows to 90 degrees and tuck them firmly against the sides of your ribcage.
- Position your forearms parallel to the floor with your palms facing each other.
How to do it
- Exhale as you slowly rotate your forearms outward away from your midline, keeping your elbows glued to your sides.
- Squeeze your shoulder blades together at the peak of the movement, feeling the contraction in your upper back and rear shoulders.
- Inhale as you slowly return your hands to the starting position in front of your body.
- Maintain a controlled tempo, focusing on a 2-second outward rotation and a 1-second squeeze.
Form checklist
- Keep your elbows pinned to your ribs throughout the entire range of motion.
- Avoid arching your lower back or flaring your ribs as you rotate outward.
- Ensure your wrists remain neutral and do not lead the movement.
- Keep your shoulders depressed and away from your ears to maximize trapezius activation.
Pro tips
- Imagine you are trying to wrap your shoulder blades around your spine to maximize the engagement of the mid-trapezius.
- Create 'internal tension' by imagining you are pulling against a heavy resistance band even though no equipment is used.
Make it harder
- Perform the exercise while standing with your back, head, and elbows pressed against a wall to enforce strict alignment.
- Add a 5-10 second isometric hold at the point of maximum external rotation.
