Setup
- Stand tall with feet shoulder-width apart and a neutral spine.
- Extend both arms straight out in front of your chest, palms facing inward toward each other.
- Position one hand directly above the other, about 8-12 inches apart, creating a vertical 'stack' with your arms.
How to do it
- Simultaneously move the top hand downward and the bottom hand upward in a straight vertical path.
- Exhale as the hands pass each other at shoulder height, maintaining constant tension in your shoulders.
- Stop once the hands have fully swapped their original vertical positions and pause for a half-second.
- Inhale as you reverse the movement back to the starting position using a slow, controlled tempo.
Form checklist
- Keep your elbows locked or with a very slight micro-bend throughout the movement.
- Maintain a tall, upright posture without leaning forward or arching your lower back.
- Keep your shoulders pulled down and away from your ears to maximize trapezius and rhomboid engagement.
- Ensure the movement is strictly vertical and the hands stay aligned with the midline of your body.
Pro tips
- Imagine you are moving your hands through thick water to create internal resistance and increase muscle fiber recruitment.
- Focus on squeezing your shoulder blades together slightly to ensure the rhomboids are active during the switch.
Make it harder
- Increase the speed of the switches while keeping your torso perfectly still to challenge core and shoulder stability.
- Hold a small household object, like a water bottle, in each hand to add light resistance to the deltoids.
