Knuckle Push-Up

Muscles worked

Setup

1. Place your fists on the floor shoulder-width apart, resting your weight specifically on the first two knuckles (index and middle fingers).
2. Extend your legs back into a high plank position with your feet hip-width apart.
3. Align your wrists directly under your shoulders, ensuring your fists are vertical and not tilted.
4. Engage your core and glutes to create a straight line from your head to your heels.

How to do it

1. Inhale and lower your chest toward the floor by bending your elbows, keeping them tucked at a 45-degree angle to your torso.
2. Continue descending until your chest is just above the floor, maintaining a neutral neck and spine.
3. Exhale and drive through your knuckles to push your body back to the starting position.
4. Maintain a controlled tempo, taking 2 seconds to lower and 1 second to push back up.

Form checklist

• Keep wrists perfectly straight; do not let them bend or roll to the side.
• Ensure the weight stays on the first two knuckles to protect the smaller bones of the hand.
• Prevent the hips from sagging or the lower back from arching by keeping the abs braced.
• Keep your gaze slightly in front of your hands to maintain a neutral cervical spine.

Pro tips

• Imagine 'punching' the floor away from you as you ascend to maximize triceps and serratus anterior recruitment.
• Actively pull your shoulder blades together on the descent and spread them apart at the top of the movement for full scapular range of motion.

Make it harder

• Elevate your feet on a bench or step to shift more weight onto the upper pectorals and anterior deltoids.
• Perform the movement with a 3-second pause at the bottom to increase time under tension and eliminate momentum.
