Equipment

  • Body weight

Setup

  1. Stand facing a wall at arm's length with your feet hip-width apart.
  2. Make firm fists and place your knuckles against the wall at shoulder height and slightly wider than shoulder-width.
  3. Step your feet back 12-24 inches to create a slight forward lean, keeping your body in a straight line from head to heels.
  4. Engage your core and glutes to stabilize your pelvis and spine.

How to do it

  1. Inhale and slowly bend your elbows to lower your chest toward the wall, keeping your elbows tucked at a 45-degree angle to your torso.
  2. Lower yourself until your forehead or chest is a few inches from the wall, maintaining a controlled 2-second tempo.
  3. Exhale as you push through your knuckles to return to the starting position, focusing on driving the wall away from you.
  4. Fully extend your arms at the top without locking out the elbows aggressively.

Form checklist

  • Keep your wrists straight and stacked directly under your forearms to avoid buckling.
  • Maintain a rigid torso; do not let your hips sag toward the wall or your glutes pike backward.
  • Keep your shoulders depressed (down away from ears) throughout the entire range of motion.
  • Distribute your weight across the first two knuckles (index and middle finger) for maximum stability.

Pro tips

  • Imagine trying to pull the wall apart with your hands as you push away to increase pectoral activation.
  • Focus on a slow eccentric (lowering) phase to maximize time under tension for the triceps and chest.

Make it harder

  • Step your feet further away from the wall to increase the percentage of body weight you are lifting.
  • Perform the movement with one arm at a time to increase the demand on your core and shoulder stabilizers.
