One-Arm Push Up
The One-Arm Push Up is a high-level bodyweight exercise that challenges strength, balance, and total body control, while producing force with a single arm.

Muscles Worked: One-Arm Push Up
The One-Arm Push Up mainly works your chest, because one pec has to drive almost the whole rep while bringing your arm toward the middle of your body. Your triceps help straighten the elbow, and your shoulders assist the press while also keeping the working arm steady. Your abs, hips, and upper back have to fight rotation hard so your torso does not twist as you lower and press back up. You should feel your chest, triceps, and whole midsection working together, and research on push-up variations shows high demand on the pressing muscles and trunk stabilizers (Freeman et al., 2006).
Technique and form
How to perform the One-Arm Push Up
- Begin in a plank position with your feet slightly wider than hip-width apart for stability, and place your working hand directly beneath your shoulder while your free arm rests against your lower back.
- Engage your core and glutes to maintain a straight line from head to heels, ensuring your hips don't sag or pike upward during the movement.
- Lower your chest toward the floor by bending your working arm elbow, keeping it close to your body at approximately a 45-degree angle from your torso.
- Inhale as you descend, maintaining tension throughout your entire body and distributing weight evenly through your supporting hand.
- Descend until your chest is about 2-3 inches from the floor, or as low as you can while maintaining proper form and body alignment.
- Push through the palm of your supporting hand, exhaling as you extend your arm to return to the starting position.
- Keep your shoulder blades stable throughout the movement, avoiding any rotation or collapsing toward the supporting side.
- Complete all repetitions on one side before switching to the other arm, maintaining consistent breathing and tension throughout each repetition.
Important information
- Master standard push-ups and progress through intermediate variations like elevated feet and diamond push-ups before attempting the one-arm push-up.
- Keep your elbow tracking in the same direction as your middle finger to protect your shoulder joint during the movement.
- Prevent rotation by actively engaging your core and squeezing your glutes throughout the entire exercise.
- If you're struggling with the full movement, start with an elevated surface for your supporting hand to reduce the difficulty level.
Is the One-Arm Push Up good for muscle growth?
Yes — if you are strong enough to do it well, the One-Arm Push Up can build serious chest, triceps, and front shoulder muscle because one side handles far more load than in a regular Push-Up. Push-up research shows that push-up variations can place high demand on the chest, triceps, and trunk stabilizers, which helps explain why advanced versions like this can be such effective bodyweight strength-builders (Freeman et al., 2006).
- High single-arm loading — With one hand off the floor, the working side takes much more of your bodyweight than in a standard push-up. That makes each rep more challenging for the chest and triceps, so advanced lifters can keep progressing even without external weight.
- Big anti-rotation demand — This is not just a chest exercise. Your abs, glutes, and upper back have to stop your body from twisting or sagging, which makes the movement harder to fake and easier to overload with clean reps.
- Longer effective reps — Because balance is the limiting factor, most people lower more carefully and pause more naturally near the bottom. That extra time under tension can make lighter bodyweight work feel much heavier on the pecs and triceps.
- Strong carryover from easier push-up variations — Building up through Decline Push-Up, close-grip work, and offset push-up progressions helps you earn the strength and body control needed here. Scapular-focused push-up training also activates the shoulder-support muscles that help keep pressing mechanics solid (Andersen et al., 2012).
Programming for muscle growth
Do 3-5 sets of 3-6 reps per side with 2-3 minutes rest. Train it 1-2 times per week, because the movement is demanding on strength, balance, and recovery. Stop each set 1-2 reps before form breaks, and if you cannot hit clean reps yet, use assisted one-arm progressions or harder two-arm push-up variations to build up first.

FAQ - One-Arm Push Up
The one-arm push-up primarily targets the pectoral muscles with extraordinary intensity, while heavily engaging the triceps and anterior deltoids. Your core also works overtime as a stabilization powerhouse, fighting rotational forces that would otherwise collapse your form.
Start with elevated one-arm push-ups (hand on a bench or box), gradually lowering the height as you build strength. Incorporate archer push-ups and uneven push-ups (one hand on a medicine ball) into your routine, while strengthening your core with anti-rotational exercises like Pallof presses.
The most common mistakes include rotating the hips/torso toward the working side, flaring the elbow outward, and insufficient core bracing. Keep your body in a straight line from head to heels, position your working hand at mid-chest level, and maintain a tight core throughout the entire movement.
Limit one-arm push-ups to 2-3 sessions per week with at least 48 hours between sessions to allow for proper recovery. Due to their intense nature, 2-4 sets of 3-5 reps per side is sufficient for most advanced trainees to stimulate growth without overtraining.
One-arm push-ups can be safe for healthy shoulders when performed with proper form, but they place significant stress on the shoulder joint. Ensure you've mastered regular push-ups, maintain a tight core to prevent shoulder destabilization, and stop immediately if you experience any joint pain rather than normal muscle fatigue.
