Setup
- Start in a high plank position with hands slightly wider than shoulder-width apart and feet hip-width apart.
- Engage your core and glutes to create a straight line from head to heels.
- Position your weight evenly across your palms and toes.
How to do it
- Lower your chest toward the floor by bending your elbows at a 45-degree angle, inhaling as you descend.
- Push back up to the starting position while exhaling forcefully.
- 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.
- 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.
