Muscles worked

Primary

  • Pectorals

Secondary

  • Erector spinae
  • Serratus anterior

Equipment

  • Body weight

Setup

  1. Start in a high plank position with hands slightly wider than shoulder-width apart and feet hip-width apart.
  2. Engage your core and glutes to create a straight line from head to heels.
  3. Position your weight evenly across your palms and toes.

How to do it

  1. Lower your chest toward the floor by bending your elbows at a 45-degree angle, inhaling as you descend.
  2. Push back up to the starting position while exhaling forcefully.
  3. At the top of the movement, rotate your torso to one side while lifting the opposite knee toward your chest and tapping it with the hand of the rotating side.
  4. Return the hand and foot to the starting plank position and repeat the push-up, alternating the rotation to the other side.

Form checklist

  • Keep the hips level and square to the floor during the push-up phase.
  • Avoid letting the lower back arch or the hips sag toward the ground.
  • Ensure the supporting shoulder remains stable and 'packed' during the rotation.
  • Control the rotation to prevent momentum from compromising your balance.

Pro tips

  • Focus on 'pushing the floor away' with the supporting arm to create maximum tension and stability during the knee tap.
  • Squeeze your obliques hard as you bring your knee toward your hand to maximize core activation and control.

Make it harder

  • Slow down the tempo, especially during the rotation and knee tap, to increase time under tension.
  • Add a two-second pause at the point of knee-to-hand contact to further challenge your stability.
