How to Ab wheel rollout

What it is

An exercise where you roll a small wheel forward, extending your body, then pull it back — while the core fights to stop the lower back from over-extending. It's one of the hardest and most effective anti-extension core exercises.

Muscles worked

Primary: Core (rectus abdominis, deep core). Secondary: Lats, Shoulders.

How to perform it

Kneel holding the wheel under your shoulders, core braced and pelvis tucked.
Roll the wheel forward as far as you can control while keeping the lower back from sagging.
Stop before your hips drop or your back arches, then reverse.
Pull the wheel back to the start by contracting the abs, staying braced throughout.

Common form faults

Letting the lower back arch and hips sag as you roll out. Only roll out as far as you can keep the pelvis tucked and back flat; shorten the range until you're stronger.
Pulling back with the hips/arms instead of the abs. Initiate the return by contracting the abs, keeping the arms and hips along for the ride.

Programming

Start from the knees with a short range and progress the distance as you get stronger; standing rollouts are an advanced goal. Train 5–12 controlled reps — quality over range.

Frequently asked questions

Why do I feel ab rollouts in my lower back?

It usually means you're rolling out further than your core can control, so the lower back arches to compensate. Shorten the range, keep the pelvis tucked, and only extend as far as you can stay braced.

How do I progress the ab wheel?

Start on your knees with a small rollout, then gradually increase the distance you roll as your core strengthens. The eventual advanced progression is rolling out from your feet rather than your knees.
