Single arm plank

The quick read

What is Single arm plank?

Single arm plank is a floor movement used in stretching and mobility sessions. People often include it when they want to bring attention to core, shoulders. Its value comes from how it fits the person and the routine, rather than how closely the body matches a picture.

The illustration offers orientation. Use your own comfortable range and leave room to breathe normally.

Use it well

How to approach the movement

A mat, rug, or folded towel can make floor contact more comfortable. Plan the transition down and back up before you begin, especially if kneeling or balance is difficult.

Enter gradually, pause where the sensation is mild and clear, and come out with the same control. Bouncing, forcing, or holding your breath usually adds effort without making the movement more useful.

Step-by-step instructions

1. Start in a hand plank with your feet wider than your hips.
2. Shift your weight into one hand and lift the other hand toward your hip.
3. Hold with your hips level, then lower and change sides.

Helpful cue

Press through the supporting hand and avoid rotating your torso.

Make it gentler

For less intensity, lower both knees to the mat and keep both arms supported.

Movement precautions

Put your hand down if your hips sag or you lose control.

When to choose another option

Stop with sharp pain, tingling, numbness, dizziness, weakness, or symptoms that travel. If you are managing an injury, recent surgery, pregnancy-related concern, joint instability, or persistent pain, ask a qualified clinician how this movement should be adapted.
