Setup
- Sit on the floor with your knees bent and feet flat on the ground, hip-width apart.
- Place your hands behind your hips, shoulder-width apart, with your fingers pointing toward your feet.
- Engage your core and pull your shoulder blades back and down to prepare for the lift.
How to do it
- Press firmly through your heels and palms to lift your hips off the floor until your torso is roughly parallel to the ground.
- Align your knees directly over your ankles and your shoulders directly over your wrists in a tabletop position.
- Exhale as you reach the peak height and maintain a neutral neck position, looking slightly upward.
- Hold the position for the prescribed duration, maintaining steady, rhythmic breathing.
Form checklist
- Keep your hips elevated and level; do not let them sag toward the floor.
- Ensure your wrists are stacked directly under your shoulders to minimize joint strain.
- Keep your chest open and avoid shrugging your shoulders toward your ears.
- Distribute your weight evenly between your hands and feet to maintain balance.
Pro tips
- Actively 'screw' your hands into the floor to create external rotation in the shoulders, which better engages the triceps and stabilizes the rotator cuff.
- Squeeze your glutes at the top of the movement to maximize hip extension and protect the lower back.
Make it harder
- Lift one leg straight out in front of you while maintaining level hips to increase core and hamstring demand.
- Transition into a 'Crab Walk' by moving opposite hands and feet simultaneously while keeping the hips elevated.
