Setup
- Stand tall with your feet shoulder-width apart and your weight evenly distributed.
- Engage your core and tuck your pelvis slightly to maintain a neutral spine.
- Let your arms hang at your sides with your palms facing your thighs and shoulders pulled down away from your ears.
How to do it
- Inhale and slowly raise both arms forward and upward in a wide, controlled arc.
- Continue the movement until your arms are fully extended overhead with your biceps aligned next to your ears.
- Exhale at the top of the range, reaching toward the ceiling while keeping your ribcage tucked.
- Lower your arms back to the starting position with a slow, 3-second controlled tempo.
Form checklist
- Keep your ribs down; do not let your lower back arch as your arms go overhead.
- Maintain straight elbows throughout the entire range of motion.
- Keep your neck neutral and gaze forward to avoid straining the cervical spine.
- Ensure your shoulders do not 'shrug' up toward your ears at the peak of the movement.
Pro tips
- Focus on 'scapular upward rotation' by feeling your shoulder blades slide out and up as you reach.
- Squeeze your glutes throughout the movement to provide a stable base and prevent lumbar compensation.
- Imagine you are trying to touch the walls in front of you as you lift to maximize the stretch in the lats.
Make it harder
- Perform the exercise with your back, head, and glutes pressed against a wall to ensure strict vertical alignment.
- Hold a light resistance band between your hands, pulling it slightly apart to increase posterior deltoid and rotator cuff activation.
