Setup
- Start in a high plank position with your hands placed directly under your shoulders.
- Position your feet slightly wider than hip-width apart to create a stable base of support.
- Engage your core and squeeze your glutes to create a straight line from your head to your heels.
How to do it
- Shift your weight slightly onto your left hand and lift your right hand to tap your left shoulder.
- Exhale as you tap, focusing on keeping your hips and shoulders perfectly square to the floor.
- Inhale as you return your hand to the starting position with control.
- Repeat the movement on the opposite side, alternating back and forth at a steady, controlled tempo.
Form checklist
- Keep your hips level; do not let them rock or tilt as you lift your hand.
- Maintain a neutral neck by looking at a spot on the floor about 6 inches in front of your hands.
- Keep your elbows slightly soft to avoid locking out the joint.
- Ensure your hands return to a position directly under your shoulders every time.
Pro tips
- Imagine there is a glass of water resting on your lower back that you cannot spill to ensure zero hip rotation.
- Actively push the floor away with your grounded hand to maximize serratus anterior activation and shoulder stability.
Make it harder
- Bring your feet closer together to decrease your base of support and increase the stability challenge.
- Slow down the tempo, pausing for 2-3 seconds at the top of the tap to maximize time under tension.
