Setup
- Place a weight plate on the floor just outside your left hand.
- Assume a high plank position with your hands directly under your shoulders and your feet slightly wider than hip-width for stability.
- Engage your glutes and core to create a straight line from your head to your heels.
How to do it
- Shift your weight onto your left hand while keeping your hips perfectly square to the floor.
- Reach your right hand across your chest, grab the plate, and slide or lift it to the outside of your right side.
- Exhale as you move the plate across your body, then place your right hand back on the floor.
- Repeat the movement with your left hand, pulling the plate back to the starting position at a controlled tempo.
Form checklist
- Keep your hips level and avoid letting them tilt or rotate as you reach.
- Maintain a neutral neck by looking at the floor about 6 inches in front of your hands.
- Do not let your lower back sag or your hips hike toward the ceiling.
- Keep the supporting arm locked out and the shoulder blade retracted and stable.
Pro tips
- Imagine a glass of water sitting on your lower back; your goal is to move the plate without spilling a drop.
- Focus on pushing the floor away with your stabilizing arm to maximize serratus anterior and deltoid engagement.
Make it harder
- Narrow your foot stance to reduce your base of support and increase the stability demand on your obliques.
- Use a heavier plate or lift the plate completely off the ground rather than sliding it.
