Setup
- Place a box or step behind you and kneel on it with both knees.
- Place your hands on the floor slightly wider than shoulder-width apart.
- Walk your hands forward until your body forms a straight line from your head to your knees.
- Engage your core and tuck your chin slightly to maintain a neutral spine.
How to do it
- Inhale as you lower your chest toward the floor by bending your elbows at a 45-degree angle to your torso.
- Continue lowering until your chest is just above the floor, maintaining a controlled 2-second descent.
- Exhale and push through your palms to return to the starting position with a 1-second tempo.
- Lock out your elbows at the top without overextending the joints.
Form checklist
- Keep your elbows tucked at a 45-degree angle; avoid flaring them out to the sides.
- Maintain a straight line from your knees to your head; do not let your hips sag or pike.
- Keep your core tight and glutes engaged to stabilize the pelvis.
- Ensure your wrists are stacked directly under your shoulders at the top of the movement.
Pro tips
- Focus on 'squeezing' the floor together with your hands as you push up to maximize pectoral contraction.
- Imagine pushing the floor away from you rather than just lifting your body weight.
- Pause for a split second at the bottom of the movement to eliminate momentum and increase intensity.
Make it harder
- Increase the height of the box to shift a higher percentage of your body weight onto your upper body.
- Slow down the eccentric phase to 4 seconds to increase time under tension for the chest and triceps.
