- Intermediate
- Compound

Setup
- Start in a high plank position with your hands placed directly under your shoulders and feet hip-width apart.
- Engage your core and glutes to create a straight line from your head to your heels.
- Maintain a neutral neck by looking at the floor approximately six inches in front of your hands.
How to do it
- Drive your right knee explosively toward your chest, then quickly retract it halfway without letting the foot touch the floor.
- Immediately drive the same knee across your body toward the opposite (left) elbow, exhaling sharply on the contraction.
- Extend the right leg fully out to the side in a 'swipe' motion, hovering the foot just above the floor, then return to the starting plank position.
- Repeat the sequence on the left side and continue alternating sides at a controlled, rhythmic tempo.
Form checklist
- Keep your hips level and avoid letting them sag or pike during the knee thrusts.
- Maintain a strong 'push' through the palms to keep your shoulder blades from winging.
- Ensure the leg is fully locked out during the lateral swipe to maximize quadriceps engagement.
- Keep your core braced as if preparing for a punch to protect the lower back.
Pro tips
- Focus on the 'crunch' sensation in your obliques during the cross-body thrust by slightly rounding the upper back.
- Slow down the 'swipe' phase to increase time under tension for the hip abductors and core stabilizers.
Make it harder
- Add a push-up between each alternating side to increase upper body and chest involvement.
- Wear ankle weights to increase the resistance during the thrust and swipe phases.
