One-Arm Push-Up

A demanding bodyweight press requiring significant chest, tricep, and core strength to perform with control.

Setup

Set up in a push-up position with feet wider than usual. A wider foot stance improves stability for the single-arm version.

Movement

Place one hand roughly under your chest's center. The other arm can be placed behind your back or extended for slight counterbalance. Lower with control, resisting the rotational pull. Your core must work hard to keep your hips and shoulders from twisting toward the floor.

Return

Press back up explosively but controlled. Maintain the straight body line throughout, same core principles as the standard push-up.

Common Mistake to Avoid

Attempting this before adequate strength is built. Weighted or deficit push-ups, and archer push-ups (a transitional one-arm-emphasis variation), are reasonable progressions first.

Equipment None (bodyweight)
Primary Muscles Chest (pectoralis major), triceps
Secondary Muscles Core (anti-rotation), front shoulders

Why it matters

Removing one arm from the push-up dramatically increases both the load on the working side and the anti-rotation demand on the core, which must resist twisting toward the floor. It's a genuine test of relative upper-body strength and a long-term goal worth building toward gradually rather than rushing.

How to do it

  1. Set up in a push-up position with feet wider than usual. A wider foot stance improves stability for the single-arm version.
  2. Place one hand roughly under your chest's center. The other arm can be placed behind your back or extended for slight counterbalance.
  3. Lower with control, resisting the rotational pull. Your core must work hard to keep your hips and shoulders from twisting toward the floor.
  4. Press back up explosively but controlled. Maintain the straight body line throughout, same core principles as the standard push-up.

Common mistakes

  • Attempting this before adequate strength is built. Weighted or deficit push-ups, and archer push-ups (a transitional one-arm-emphasis variation), are reasonable progressions first.
  • Letting the hips rotate toward the floor. If your body twists significantly, the core isn't yet strong enough to control the movement safely.
  • Placing the working hand too far to one side. A hand placed too far out from center makes the movement mechanically much harder and less stable.
  • Sacrificing range of motion to complete the rep. A partial rep with poor control isn't building the same strength as a controlled full rep.

Sets & reps by level

Beginner

Not applicable — build toward this with archer push-ups and other progressions first.

Intermediate

Not typically achievable yet — focus on progressions (archer push-ups, elevated one-arm push-ups) for 3 sets of 5–8 reps per side.

Advanced

3–4 sets of 3–6 reps per side once full one-arm push-ups are achievable with strict form.
