One-Arm Incline Push-Up — support ~20 cm

Push horizontal · reps · unilateral Second-to-last incline. The press feels close to a true floor one-arm push-up. Maximal tension and honest range are everything here.

The movement

One hand on a stable surface around 20 cm (single aerobic step, low crate), body nearly horizontal. Build full tension before each rep, controlled descent to the edge, firm lockout. The free hand is entirely passive on the back.

Set-up — and what each part is for

  • Face a stable surface at roughly 20 cm with a free edge. Working hand under its shoulder.
  • Feet on the balls of the feet, heels lifted, toes forward, shoulder-width.
  • Distance to support (relative). Straight-line rule. Re-measure for this height and store the distance.
  • Free hand parked.
  • Body one straight line. Glutes squeezed, abdominals braced. Pelvis square.
  • Working shoulder packed down; hand screwed into the edge.
  • Head neutral, clearing the edge.

The rep — rehearse it before you do it

  • Down (1–2 s). Build full tension before initiating the descent. Elbow ~45°, chest toward the edge. → Feel a near-maximal demand in the working arm and chest, with the trunk’s anti-rotation brace working hard the entire rep.
  • Bottom. Chest at the edge, brief still pause. → Feel this is the real thing at a small advantage; the floor is close.
  • Up. Press by screwing the hand into the support; full lockout, no twist.

Watch for

  • Shoulder collapsing at the bottom → packed shoulder, lat engaged.
  • Jerks or kips on the way up → press cleanly or end the set.
  • Free hand sneaking in to help → it stays parked.
  • Elbow flaring under fatigue → hold ~45°.

Breathing

Inhale and brace at the top; strong sharp exhale through the press.

Within the level

  • Harder: 3 s descent; pause at the bottom; narrow the feet.
  • Easier: widen the feet. If balance is the limiter, rest the free-hand fingertips on the support, reducing contact over time.

Dose

Test a clean max on each side; work at half of the weaker side (rounded down), max 5 reps per set, same count both sides, weaker side first, spread through the day. Stop each set well short of failure.
