Setup
- Start in a high plank position with your hands placed directly under your shoulders.
- Engage your core and glutes to form a straight line from your head to your heels.
- Position your feet hip-width apart with your weight on the balls of your feet.
How to do it
- Exhale as you step your right foot forward, placing it flat on the floor just outside your right hand.
- Inhale as you step the right foot back to the starting plank position with control.
- Repeat the movement on the left side, stepping the left foot outside the left hand.
- Maintain a steady, rhythmic tempo, alternating sides while keeping your chest open.
Form checklist
- Keep your hips low and level with your shoulders throughout the transition.
- Ensure the front foot lands flat on the floor to protect the knee and engage the glute.
- Keep your arms locked out and push the floor away to engage the serratus and deltoids.
- Maintain a neutral neck by looking at a spot about 6 inches in front of your hands.
Pro tips
- Actively drive the heel of your back leg toward the wall behind you to maximize the stretch in the hip flexors.
- Focus on 'pulling' your knee forward using your lower abdominals rather than just swinging the leg.
Make it harder
- Increase the pace to a 'jumping' switch where both feet leave the ground simultaneously to transition.
- Add a brief pause in the lunge position to deepen the stretch and increase isometric time under tension.
