Setup
- Stand with feet hip-width apart and a slight bend in your knees.
- Hinge forward at the hips until your torso is almost parallel to the floor, maintaining a flat back.
- Let your arms hang directly below your shoulders with palms facing each other and elbows slightly unlocked.
How to do it
- Exhale and raise your arms out to the sides in a wide arc until they are level with your shoulders.
- Squeeze your shoulder blades together at the peak of the movement for one second.
- Inhale as you slowly lower your arms back to the starting position using a controlled 2-3 second tempo.
Form checklist
- Keep your spine neutral and avoid rounding your lower back.
- Lead the movement with your elbows rather than your hands.
- Keep your neck tucked to look at the floor, avoiding neck strain.
- Ensure the movement comes from the shoulders, not by swinging the torso.
Pro tips
- Imagine trying to touch the side walls with your knuckles to maximize the lever length and tension.
- Focus on the 'squeeze' between the shoulder blades to ensure the trapezius is fully engaged alongside the rear delts.
Make it harder
- Incorporate a 5-second isometric hold at the top of every rep to increase time under tension.
- Perform the exercise with a 'thumbs down' hand orientation to further isolate the posterior deltoid.
