One-Arm Push Up

Published: May 29, 2025 · Updated: Mar 15, 2026

The One-Arm Push Up is an advanced bodyweight exercise that demands exceptional strength, balance, and full-body rigidity. Shifting all pressing work to a single arm dramatically increases the demand on the chest, shoulder, and triceps of the working side. Reducing the base of support also forces much higher core activation — spine loading and trunk muscle demands increase substantially compared to bilateral push-up variations (Freeman et al., 2006).

Maintaining a rigid body line from head to heel is critical throughout each rep. The free arm assists with balance, while the working arm controls both the lowering and pressing phases. Moving deliberately prevents rotation and keeps tension on the target muscles. Progressive calisthenic push-up training has been shown to produce meaningful gains in both muscle strength and thickness over time (Kotarsky et al., 2018).

This movement is best suited for experienced athletes building unilateral pressing strength or pursuing high-level bodyweight goals. It works as a progression target, a strength benchmark, or a challenging variation within calisthenics routines and minimal-equipment workouts.

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.

Common Mistakes: One-Arm Push Up

Flaring your elbows too wide

Keep your elbows at a moderate angle rather than pushing them straight out to the sides. This protects your shoulder joints.

Arching your lower back excessively

A slight natural arch is fine, but over-arching means you're using too much weight. Brace your core and reduce the load.

Progressing too fast

Master the basic version before trying harder variations. Build a solid foundation first.

Rushing through reps

Slow, controlled reps work the muscle much better than fast, sloppy ones. Take your time on both the lifting and lowering phase.

Holding your breath

Breathe out during the hard part of the movement and breathe in as you return to the start. Holding your breath can spike your blood pressure.

Benefits of the One-Arm Push Up

Builds stronger chest muscles

The One-Arm Push Up directly targets your chest muscles, helping you build strength and size in this area over time.

Compound movement for real-world strength

Because the One-Arm Push Up uses multiple joints and muscles together, the strength you build transfers directly to everyday activities and sports performance.

Increases overall strength

Regularly performing the One-Arm Push Up with progressive weight builds functional strength that carries over to other exercises and daily life.

Equipment advantage

Using your own bodyweight makes this exercise accessible anywhere without equipment, giving you a training benefit that's hard to replicate with other setups.

Train anywhere

The One-Arm Push Up can be done at home with minimal or no equipment, making it easy to stay consistent even when you can't get to the gym.

Muscles Worked: One-Arm Push Up

The One-Arm Push Up is a compound exercise that engages multiple muscle groups working together. Here's how each muscle contributes to the movement.

Primary muscles

Pecs — Your chest muscles power the pushing motion. These are the main muscle doing the heavy lifting during the One-Arm Push Up.

Secondary muscles

Triceps — Your triceps extend your elbows and lock out the movement. While not the main focus, these muscles play an important supporting role.

Front Delts — Your front shoulder muscles assist in lifting the weight overhead or forward. While not the main focus, this muscle plays an important supporting role.

The One-Arm Push Up primarily works 1 muscle with 2 supporting muscles assisting the movement.

FAQ - One-Arm Push Up

What muscles does the one-arm push-up work?

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.

How can I progress toward a one-arm push-up if I can't do one yet?

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.

What are the most common form mistakes with one-arm push-ups?

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.

How often should I include one-arm push-ups in my training routine?

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.

Are one-arm push-ups safe for my shoulders?

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.
