Setup
- Stand facing a wall or a sturdy elevated surface with feet hip-width apart.
- Place your hands on the surface at shoulder height, slightly narrower than shoulder-width apart.
- Step your feet back until your body is at a diagonal incline with your weight on the balls of your feet.
How to do it
- Inhale and slowly bend your elbows to lower your head toward your hands, keeping your upper arms fixed in place.
- Lower yourself until your forearms are nearly parallel to the wall or you feel a deep stretch in the triceps.
- Exhale and push through your palms to fully extend your arms back to the starting position.
- Maintain a controlled tempo, taking 3 seconds to lower and 1 second to extend.
Form checklist
- Keep your elbows pointed down toward the floor, not flared out to the sides.
- Maintain a neutral spine and tight core to prevent your hips from sagging or your back from arching.
- Ensure the movement occurs only at the elbow joint; your shoulders should remain stable.
- Keep your shoulders depressed and away from your ears throughout the set.
Pro tips
- Focus on 'pushing the wall away' rather than just pushing yourself up to maximize tricep fiber recruitment.
- Pause for a split second at the bottom of the movement to eliminate momentum and increase time under tension.
Make it harder
- Lower the height of your hands by using a bench or a low rail to increase the percentage of body weight being lifted.
- Perform the exercise one arm at a time to increase the stability demand and double the resistance on the working tricep.
