Setup
- Stand with your feet shoulder-width apart and a slight bend in your knees.
- Engage your core and maintain a neutral spine with your gaze fixed forward.
- Extend both arms straight out in front of you at shoulder height, palms facing down.
How to do it
- Reach one arm forward while pulling the opposite elbow back in a rowing motion, rotating your torso slightly toward the pulling side.
- Exhale as you pull the arm back, focusing on driving the elbow behind the body and squeezing the shoulder blade toward the spine.
- Inhale as you reach the back arm forward to return to the starting position, alternating sides in a fluid, rhythmic motion.
- Maintain a controlled tempo, focusing on the 'catch and pull' sensation as if moving through water.
Form checklist
- Keep your hips facing forward; the rotation should come from the mid-back (thoracic spine).
- Avoid shrugging your shoulders toward your ears to keep the traps relaxed.
- Keep your core tight to prevent excessive arching of the lower back during the reach.
- Ensure your arms stay at or near shoulder height throughout the entire movement.
Pro tips
- Imagine you are pulling against heavy water to increase the mind-muscle connection in your lats and serratus anterior.
- Focus on the maximum 'reach' at the top of the movement to fully engage the serratus anterior and stretch the lats.
Make it harder
- Perform the movement while holding light dumbbells or wearing wrist weights to increase resistance.
- Slow the tempo to a 4-second reach phase to maximize time under tension and stability requirements.
