It builds exceptional trunk stiffness while taxing the shoulders and lower body through rapid, explosive transitions.

Setup
- Start in a high plank position with your hands placed slightly wider than shoulder-width apart.
- Stack your shoulders directly over your wrists and engage your glutes to create a straight line from head to heels.
- Position your feet together, resting on the balls of your feet with your core braced tightly.
- Maintain a neutral neck by gazing at a point about 6 inches in front of your hands.
How to do it
- Exhale sharply and explosively jump both feet out wide, landing softly on your toes while keeping your hips level.
- Immediately jump both feet back to the starting position without letting your lower back arch or your hips sag.
- Maintain a rapid, rhythmic tempo, ensuring your upper body remains completely still and braced throughout the movement.
- Inhale during the transition and exhale on each explosive jump outward.
Form checklist
- Keep your hips level with your shoulders; do not let them bounce up or dip down.
- Ensure your wrists, elbows, and shoulders stay in a straight vertical line.
- Maintain a 'hollow body' position by pulling your belly button toward your spine.
- Avoid locking out your elbows completely; keep a micro-bend to protect the joints.
Pro tips
- Focus on 'pushing the floor away' through your palms to maximize serratus anterior and pectoral engagement.
- Minimize the sound of your feet hitting the floor; the quieter the landing, the more your core is controlling the deceleration.
- Imagine a glass of water resting on your lower back; your goal is to move your legs without spilling a drop.
Make it harder
- Perform the movement with your hands on an unstable surface like a BOSU ball or medicine ball.
- Add a 'Plank Jack to Tuck' by alternating the wide jump with a jump bringing both knees toward your chest.
