Setup

  1. Begin in a high plank position with your hands placed directly under your shoulders.
  2. Extend your legs fully with feet hip-width apart, creating a straight line from your head to your heels.
  3. Engage your glutes and pull your belly button toward your spine to stabilize your pelvis.

How to do it

  1. Exhale as you lift one foot and bring your knee toward the outside of the ipsilateral (same side) elbow.
  2. Keep your leg parallel to the floor as you move, focusing on 'crunching' your side to bring the knee forward.
  3. Inhale as you return your foot to the starting position with control, avoiding any hip sagging.
  4. Repeat the movement on the opposite side and continue alternating at a slow, controlled tempo.

Form checklist

  • Keep your hips level and square to the floor; do not let them rotate or pike up.
  • Ensure your knee travels laterally (out to the side) rather than underneath your chest.
  • Maintain a neutral neck by gazing at a point on the floor about 6 inches in front of your hands.
  • Keep your shoulders stacked directly over your wrists throughout the entire set.

Pro tips

  • Imagine trying to touch your knee to your shoulder to maximize the contraction in your obliques.
  • Actively push the floor away with your hands to keep your shoulder blades spread and your upper back engaged.
  • Pause for one second at the peak of the movement to increase time under tension for the core.

Make it harder

  • Perform the movement from a low plank (forearms) to increase the difficulty of the lateral knee drive.
  • Add a push-up simultaneously as the knee comes forward to transition into a Spiderman Push-up.
