The single arm push-up — also called the one-arm push-up — is the gold standard of bodyweight pressing strength. To do a clean one, you have to press roughly 70% of your body weight on a single arm while resisting the rotational forces that try to twist your trunk. Most people who can bench their body weight still can't do a single one-arm push-up, because the strength curve, balance demands, and core stabilization required are completely different from any barbell movement. Reaching a clean one-arm push-up typically takes 1-3 years of dedicated calisthenics training from a base of 30+ standard push-ups. The progression isn't linear: archer push-ups, then assisted one-arm push-ups (with the off-hand on a higher surface or band-assisted), then negative-only one-arm push-ups, then partial-range one-arm push-ups, then finally a full clean rep. Trying to skip steps usually ends in shoulder strain. What makes the movement legendary is what it represents — true strength-to-weight ratio. The exercise rewards consistency, patience, and a willingness to do unsexy progression work for months between visible breakthroughs. For most people, working toward a one-arm push-up over a year does more for total upper body strength than any other single goal in calisthenics.

Why train the Single Arm Push-up?

Builds maximal pressing strength relative to body weight, with no equipment required.
Develops anti-rotation core strength at a level few exercises match.
Trains shoulder stability and serratus activation under unilateral load.
Carries over to almost every other pressing exercise — bench, dumbbell, dips — because of the strength base it builds.
Provides clear progression milestones that drive long-term training motivation.
Makes regular two-arm push-ups feel trivial as a side effect, doubling your useful rep range.

How to do the Single Arm Push-up: step by step

1Start in a push-up position with your hands shoulder-width apart and one hand placed slightly wider than the other.
2Engage your core and lower your body towards the ground by bending your elbows, keeping your back straight.
3As you lower yourself, shift your weight to one side and lift the opposite arm off the ground, extending it straight out to the side.
4Push through your chest and triceps to raise your body back up to the starting position, while simultaneously lowering your extended arm back to the ground.
5Repeat the movement, alternating the arm you extend with each repetition.

Common mistakes to avoid

Twisting the trunk to fake the rep
When the working arm can't handle the load, the body rotates so the chest faces the floor at an angle, reducing the load. Keep the chest, shoulders, and hips square to the floor — if you can't, you're not ready and should regress to assisted versions.
Spreading the feet too narrow
Narrow feet make the balance demand impossible. Start with feet about 2-3 feet apart for early one-arm push-up work; narrow them gradually as your stability improves over months.
Letting the elbow flare wide
Wide elbow loads the rotator cuff in a vulnerable position. Keep the working elbow at roughly 30-45 degrees from the torso through the entire press.
Rushing the descent
Dropping into the bottom uses momentum and risks shoulder injury. Take 2-3 seconds to lower into every rep, controlling the descent. The eccentric phase is where you build the strength to push back up.
Skipping the prerequisite work
Most one-arm push-up failures come from people who couldn't yet do clean archer push-ups or assisted one-arms. Don't attempt the full movement until you have 5-8 strict archers per side.

Easier and harder variations

Easier

Archer push-ups (wide hands, one arm doing most of the work per rep) are the standard regression. Then assisted one-arm push-ups with the off-hand on a low elevated surface (a step or yoga block). Then negative-only one-arm push-ups (slow descent, push back up with both arms).

Harder

Reduce the foot stance further toward shoulder-width. Add weight (a vest or plate). Or progress to one-arm one-leg push-ups — same arm work, even more anti-rotation demand.

Alternative exercises

Archer push-up
The most direct stepping stone. Wide hand stance with one arm doing 80%+ of the work. Build to 5-8 strict archers per side before attempting one-arm.
Pseudo-planche push-up
Hands shifted toward the hips, fingers pointed back. Builds shoulder strength and forearm stability needed for advanced one-arm work.
Weighted push-up
Add a vest or plate for progressive overload on standard push-ups. Builds raw pressing strength that supports unilateral progression.

How to program the Single Arm Push-up into your training

One-arm push-up training is low-rep, high-effort, and demands long recovery. Once you've achieved your first rep, programming should respect that. Early phase (first 1-3 reps possible): 4-5 sets of 1-2 reps per side, twice per week, with 2-3 minutes rest between sets. Don't chase reps — chase quality. Pair with archer push-ups or assisted one-arms for volume work in the same session. Building phase (3-6 reps possible): 4-5 sets of 2-4 reps per side, twice per week. Once you hit 3 sets of 5 strict reps per side, start adding weight (a light vest) instead of more reps. Loaded one-arm push-ups produce strength gains faster than higher reps. Maintenance phase (6+ clean reps): Reduce to once per week as a focused session, with archer push-ups as the secondary work. The strength is hard-won; you don't need to train it twice a week to keep it. Always pair one-arm push-up training with horizontal pulling — heavy rows or pull-ups — to keep the shoulders balanced. Unilateral pressing without enough pulling work creates postural and rotator cuff issues over time. For the progression toward your first rep, run cycles of 6-10 weeks alternating between strength-focused training (heavy archer push-ups, 4 sets of 4-6 reps) and skill-focused training (negative one-arms, low reps, focus on form).

Recovery and frequency

One-arm push-ups are demanding on the chest, anterior delts, triceps, and especially the rotator cuff. 72 hours between dedicated sessions is the right cadence — push beyond that and most people develop shoulder issues that interrupt training for weeks. The wrist and elbow of the working arm take significant load. Spend 2-3 minutes on wrist mobility before every session, and don't ignore elbow tendinopathy if it develops — back off frequency or volume immediately if you feel it. Foam roll the chest, lats, and triceps weekly to maintain the soft tissue mobility this kind of training compresses. Sleep is the biggest recovery lever; 8+ hours during heavy one-arm push-up training phases is non-negotiable.

Frequently asked questions

How many sets and reps of one-arm push-ups should I do?

When you first achieve the movement, expect 4-5 sets of 1-2 reps per side. Build to 5-6 reps per side over 6-12 months before adding weight or reducing foot stance.

How often should I train the one-arm push-up?

1-2 times per week max, with 72 hours between sessions. The shoulders take longer to recover from this load than from any standard push-up volume.

How long does it take to learn a one-arm push-up?

From a base of 30+ standard push-ups, expect 12-24 months of progression work (archer push-ups, assisted one-arms, negatives). From scratch, plan on 2-3 years. Body composition matters — heavier trainees take longer because the absolute load is higher.

Should I learn the archer push-up first?

Yes — archer push-ups are the essential prerequisite. Build to 5-8 strict archers per side before serious one-arm push-up training. Skipping this step is the most common reason progression stalls.

Are one-arm push-ups bad for the shoulders?

Done with proper progression and adequate recovery, no — they build shoulder stability. Done by attempting the full movement before prerequisites are in place, yes — rotator cuff strains are common in rushed trainees. The risk is in skipping steps, not in the exercise itself.

Will body weight affect my ability to do one-arm push-ups?

Significantly. The exercise is body-weight-relative, so a 200-lb trainee has to press 140 lb on one arm vs. a 150-lb trainee pressing 105 lb. Lighter, leaner trainees usually achieve their first one-arm push-up faster, all else equal.
