One-Arm Push-Up — Narrow Stance
Push horizontal · reps · unilateral The endpoint of the chain. Feet close, body a rigid plank, zero twist. From here you maintain rather than progress.
The movement
On the floor, feet narrow, working hand under its shoulder, the other parked behind the back. Lower the chest to the floor and press back, on one arm, body moving as one rigid block with the pelvis perfectly square from start to finish. Do all reps on one side, then switch.
Set-up — and what each part is for
- Feet on the balls of the feet, heels lifted, hip-width or together.
- Working hand flat on the floor under its shoulder.
- Free hand parked firmly in the small of the back.
- Body one straight line. Glutes squeezed, abdominals braced hard — this narrow base forgives nothing. Pelvis square.
- Working shoulder packed down; hand screwed into the floor; armpit closed, lat engaged.
- Head neutral, gaze to the floor a little ahead.
The rep — rehearse it before you do it
- Down (2–3 s). Build full tension before initiating the descent. Elbow ~45°, forearm vertical at the bottom. → Feel the load run straight down the arm into the floor, off the front of the shoulder; the whole body contributes, nothing is relaxed.
- Bottom. Chest grazes the floor, brief still pause. → Feel a maximal whole-body pressing effort wrapped in a maximal anti-rotation brace; the narrow base exposes any twist instantly.
- Up. Press to a complete lockout, screwing the hand, closing the armpit, squeezing the glutes. No twist toward the working side, no drift toward the free side.
Watch for
- Trunk twisting toward the working side — the dominant fault at this stance.
- Free-side hip opening toward the ceiling → both hips parallel to the floor.
- Range shortened or elbow flaring to a T → full range, elbow tucked.
- Free arm escaping → it stays parked; momentum voids the rep.
Breathing
Inhale and brace at the top; a brief held breath at the bottom stabilises the trunk under maximum load; a single decisive sharp exhale through the hardest part of the press.
Within the level
The endpoint stays active after the criterion is met; these keep it productive without leaving it.
- Harder: 3 s descent; dead-start from the floor; paused isometric at the bottom; external load once it can be tracked.
- Easier: widen the stance toward shoulder-width. Slow negatives build the rep when fresh singles are not available.
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. At this load the daily set is typically a single clean rep per side. Stop each set well short of failure.
