Setup
- Stand tall with your feet shoulder-width apart and your core engaged to stabilize your spine.
- Extend your arms straight out to your sides at shoulder height, forming a 'T' shape with your body.
- Position your palms facing downward and keep your neck in a neutral position.
How to do it
- Begin drawing large, controlled circles with your fingertips, moving your arms forward, upward, backward, and then down.
- Inhale as your arms move through the upward phase of the circle and exhale as they sweep downward.
- Maintain a slow, deliberate tempo, ensuring the movement is fluid and the arms remain at shoulder height or higher.
- Complete the set in one direction, then reverse the rotation to move in the opposite direction.
Form checklist
- Keep your arms fully extended throughout the entire rotation without locking the elbows.
- Avoid shrugging your shoulders toward your ears; keep your shoulder blades pulled down and back.
- Maintain a vertical torso and avoid arching your lower back as your arms move behind you.
- Ensure the rotation occurs at the shoulder joint rather than just moving the wrists or forearms.
Pro tips
- Focus on 'reaching' outward through your fingertips to maximize the stretch in the pectorals and engagement of the serratus anterior.
- Actively squeeze your shoulder blades together as your arms pass behind the midline of your body to better engage the trapezius and rhomboids.
Make it harder
- Hold light weights or small water bottles to increase the gravitational load on the deltoids.
- Slow the tempo significantly to increase time under tension, focusing on the furthest reaches of your range of motion.
