Setup

  1. Start in a high plank position with your hands directly under your shoulders and feet slightly wider than hip-width apart.
  2. Engage your core and glutes to create a straight line from your head to your heels.
  3. Distribute your weight evenly across your palms and the balls of your feet.

How to do it

  1. Simultaneously lift your right hand and left foot, rotating your torso to the right while pivoting on your right foot.
  2. Exhale as you 'kick' your left leg through the space under your body, extending it fully while keeping your chest open.
  3. Inhale as you retract the leg and return to the starting high plank position with control.
  4. Repeat the movement on the opposite side, alternating in a fluid, rhythmic motion.

Form checklist

  • Keep the supporting shoulder 'packed' and stable, pushing the floor away.
  • Rotate your hips fully so they face the side wall at the peak of the kick.
  • Maintain a tight core to prevent your hips from sagging toward the floor.
  • Ensure the pivoting foot turns fully to protect the knee and ankle joints.

Pro tips

  • Focus on the mind-muscle connection in your obliques; they should drive the rotation, not just your legs.
  • Keep the kicking leg as straight as possible and flex your toes toward your shin to maximize quad and lower-abdominal engagement.

Make it harder

  • Increase the tempo to transform the movement into a high-intensity cardiovascular challenge.
  • Keep the kicking foot hovering two inches off the floor throughout the entire rotation to significantly increase core tension.
