Equipment
Setup
- Start in a forearm plank position with your elbows directly under your shoulders and forearms parallel.
- Place your feet slightly wider than hip-width apart to create a stable base for the rotational challenge.
- Engage your glutes and core to create a straight line from your head to your heels.
How to do it
- Exhale and shift your weight slightly onto your left forearm while lifting your right hand off the floor.
- Reach back with your right hand to tap your right thigh, keeping your hips perfectly square to the ground.
- Inhale as you return your right forearm to the starting position with control.
- Repeat the movement on the left side, alternating arms at a slow, controlled tempo.
Form checklist
- Keep your hips level; do not let them rotate or tilt as you lift your arm.
- Maintain a neutral neck by looking at the floor just in front of your hands.
- Avoid hiking your hips toward the ceiling or letting your lower back sag.
- Push actively through the supporting elbow to prevent your shoulder from collapsing.
Pro tips
- Imagine a glass of water resting on your lower back; your goal is to move your arm without spilling a drop.
- Focus on 'bracing' your core as if someone is about to punch you in the stomach to maximize muscle recruitment.
Make it harder
- Narrow your foot stance to decrease your base of support, significantly increasing the stability demand.
- Hold the thigh tap for 2-3 seconds to increase the time under tension for the stabilizing muscles.
