Setup
- Lie flat on your back on a mat with your knees bent and feet flat on the floor to stabilize your spine.
- Grasp a stick or PVC pipe with an overhand grip, hands spaced shoulder-width apart.
- Rest the stick across your upper thighs with your arms fully extended and elbows locked.
How to do it
- Inhale and slowly raise the stick in a wide arc toward the ceiling and then back over your head toward the floor.
- Lower the stick as far as your mobility allows without your lower back lifting off the ground.
- Exhale as you slowly reverse the movement, returning the stick to the starting position on your thighs.
- Maintain a controlled 3-second tempo for both the lifting and lowering phases.
Form checklist
- Keep your lower back pressed firmly against the floor throughout the entire movement.
- Ensure your elbows remain fully locked and do not bend as you reach overhead.
- Keep your shoulders pulled down away from your ears to avoid shrugging.
- Move only within a pain-free range of motion; do not force the stretch.
Pro tips
- Focus on 'reaching' long through your arms to maximize the stretch in the lats and serratus anterior.
- Use the stick to ensure both arms move symmetrically, preventing your dominant side from doing all the work.
Make it harder
- Narrow your grip on the stick to increase the intensity of the stretch and the demand on shoulder mobility.
- Pause for 3-5 seconds at the bottom of the overhead position to deepen the stretch under control.
