You’ve seen it in movies. Rocky Balboa does them in a dingy gym while trumpets blare. Bruce Lee made them look like a casual warm-up. But honestly, if you walk into your local commercial gym right now, you probably won't see a single person doing a one armed push up with anything resembling good form. Most people who try just end up doing a weird, flailing seizure-type movement where their hips sag and their shoulder screams for mercy. It’s not just about raw strength. It’s a full-body coordination puzzle that most people fail to solve because they treat it like a regular push up with one hand behind their back. That's a mistake.
The Brutal Truth About Leverage and Tension
A standard push up requires you to move roughly 65% of your body weight. When you drop to one arm, you aren't just doubling the weight on that limb. You're fighting physics. Your body wants to rotate. Gravity is trying to pull your free shoulder toward the floor, and your core has to act like a rigid bridge to stop that from happening.

If you don't have a rock-solid plank, you'll never nail the one armed push up. Pavel Tsatsouline, the guy who basically brought kettlebells to the West, often talks about "irradiation." This is the idea that by clenching your fist, your abs, and your glutes, you actually make your working arm stronger. It’s a neurological trick. Without it, you’re just a wet noodle trying to push a heavy rock. You need to create total body tension.
Most guys think they need a massive chest. Sure, that helps. But the real secret is the serratus anterior and the obliques. These muscles keep your ribcage stable. If they fail, your form collapses, and your shoulder joint takes the brunt of the force. That's how injuries happen. Don't be that person.
Why Your Feet Are Probably Too Close Together
In a normal push up, your feet are together. In a one armed push up, if you keep your feet together, you will fall over. It is physically impossible for most humans to balance that way because the center of mass shifts dramatically. You need a wide base. We’re talking wider than shoulder-width.
Think of it like a tripod. Your feet and your single hand create a triangle. The wider that triangle, the more stable you are. As you get stronger—and I mean really stronger—you can start to bring your feet closer together. But for now? Spread 'em. It’s not cheating; it’s mechanics.
The "Anti-Rotation" Secret
The biggest hurdle isn't the "push." It’s the "staying flat." Your torso should stay parallel to the floor. If your torso twists so much that your chest is facing the wall, you aren't doing a one armed push up. You're doing a weird, vertical pressing movement that puts your rotator cuff in a meat grinder.
Focus on your opposite hip. If you’re pushing with your right hand, your left hip is going to want to dip toward the ground. Fight that. Pull that left hip up. Brace your core like someone is about to kick you in the stomach. This "anti-rotation" is the hallmark of someone who actually knows what they're doing.

A Realistic Progression That Won't Trash Your Shoulders
You can't just "try" this move and hope for the best. You need a ladder. Start with Incline One Armed Push Ups. Use a kitchen counter, a weight bench, or even a sturdy table. The higher the surface, the easier the move. This allows you to practice the balance and the tension without having to move your entire body weight against the full force of gravity.
Once you can do 10 clean reps on a bench, move to a lower step.
Eventually, you'll get to the floor. But even then, don't go for the full rep yet. Try Archers. An Archer push up is where one arm stays straight and acts as a kickstand while the other arm does the heavy lifting. It's a bridge. It teaches your brain how to shift weight to one side.
- Phase 1: High Incline (Wall or Counter)
- Phase 2: Low Incline (Bench or Stairs)
- Phase 3: Archer Push Ups on the floor
- Phase 4: Negative-only one armed push ups (Lower yourself slowly, then use both hands to get back up)
Negatives are where the magic happens. Research into eccentric loading shows that you can handle more weight on the way down than on the way up. By spending 5 seconds lowering yourself to the floor on one arm, you're building the specific connective tissue strength required for the "up" part. Just don't overdo it. Two or three negatives per set is plenty. It’s taxing on the nervous system.
The Hand Placement Nobody Talks About
Where do you put your hand? Most people put it right under their shoulder. That’s okay, but if you want more power, try turning your fingers slightly outward. Not a lot. Maybe 10 to 15 degrees. This opens up the shoulder joint and allows your elbow to tuck closer to your ribs.
If your elbow flares out 90 degrees, stop. You’re asking for an impingement. Keep that elbow tucked. Think of it like a 45-degree angle from your body. This engages the triceps and the lats more effectively. Yes, your lats. A strong one armed push up actually uses the big muscles in your back to stabilize the descent.
Common Pitfalls and Mental Cues
Stop looking at the floor right beneath your hand. Look about a foot in front of you. This keeps your spine neutral. If you tuck your chin to your chest, you’ll round your upper back, and your power will leak out.
And for the love of all things holy, squeeze your glutes. I can't stress this enough. If your butt is soft, your lower back will arch, and you’ll look like a dying seal. A tight posterior chain is the "secret sauce" of calisthenics.
Remember:
- Feet wide.
- Glutes tight.
- Core braced.
- Slow descent.
- Explosive ascent.
If you can't explode up, you aren't ready for that level of the progression yet. Go back to the incline. There is no shame in using a bench for six months. It's better than a torn labrum.
Practical Steps to Your First Rep
Don't train this every day. It's a high-intensity move. Treat it like a heavy bench press or a deadlift. Twice a week is plenty.
Start your workout with your one armed push up practice while you’re fresh. Do 3 sets of 3–5 reps of whatever progression you're currently on. If you're doing negatives, do 3 sets of 2 reps. Focus on the quality. If your form breaks, the set is over. No "grinding" through bad form here.
Once you’ve finished your specific practice, move on to your regular accessory work—things like overhead presses, pull-ups, and core work. Within 8 to 12 weeks of consistent, focused practice, that "impossible" move will start to feel like second nature. You won't just be strong; you'll have the kind of functional, coordinated power that few people ever bother to build.
The path to a one armed push up isn't about doing more push ups. It's about mastering your own tension. Start today by finding a sturdy kitchen counter and testing your balance. You might be surprised at how much work your core has to do just to keep you from tipped over. That's the first step. Take it.
