Setup
- Start on all fours, then lower your forearms to the ground with elbows positioned directly under your shoulders.
- Extend your legs back one at a time, feet hip-width apart, to enter a standard forearm plank position.
- Align your head, upper back, and glutes in a straight line with a neutral spine.
How to do it
- Exhale as you push through your forearms to actively round your upper back toward the ceiling, spreading your shoulder blades as wide as possible.
- Hold the peak protracted position for 1-2 seconds, maintaining a rigid core and level hips.
- Inhale as you slowly lower your chest back to a neutral plank position, allowing the shoulder blades to return to center without sagging.
- Repeat the movement for the desired duration, following a controlled 2-1-2 tempo (2s up, 1s hold, 2s down).
Form checklist
- Keep the core braced and glutes squeezed to prevent the lower back from arching.
- Ensure the movement comes only from the shoulder blades, not by hiking the hips.
- Maintain a neutral neck by looking at the floor between your wrists.
- Keep your elbows stacked directly under your shoulders to avoid joint strain.
Pro tips
- Imagine you are trying to push the floor away from your body to maximize serratus anterior engagement.
- Focus on the 'hollow body' sensation at the top of the movement to better recruit the deep abdominals.
Make it harder
- Elevate your feet on a bench or stable platform to shift more weight onto the shoulders and upper back.
- Perform the protraction while holding a single-leg plank to increase the stability demand on the core and obliques.
