Setup

  1. Begin in a high plank position with your hands stacked directly under your shoulders.
  2. Position your feet together and engage your glutes to create a straight line from head to heels.
  3. Spread your fingers wide and press firmly into the floor to stabilize your upper body.

How to do it

  1. Keeping your feet together, jump both feet forward and to the outside of your right hand while exhaling.
  2. Inhale as you immediately jump both feet back to the center starting plank position.
  3. Repeat the movement by jumping both feet to the outside of your left hand.
  4. Continue alternating sides at a controlled, rhythmic tempo.

Form checklist

  • Keep your shoulders directly over your wrists throughout the movement.
  • Land softly on the balls of your feet to minimize impact.
  • Avoid letting your hips sag toward the floor when returning to the plank.
  • Maintain a neutral neck by looking at a point slightly in front of your hands.

Pro tips

  • Focus on driving your knees toward your triceps to maximize oblique contraction.
  • Maintain a tight 'hollow body' position in the center plank to protect your lower back.
  • Minimize the time your feet spend on the ground to increase the metabolic demand.

Make it harder

  • Increase the pace to a 'sprint' tempo while maintaining full range of motion.
  • Add a push-up every time you return to the center plank position.
