Muscles worked

The prime movers are the rectus abdominis and the obliques, which flex the trunk forward and resist it being pulled into extension or twisted out of line.

How this movement works

One joint changes angle and the resistance travels toward you along a single arc. Nothing is positioned to help, so tension stays where you aimed it and the usable load drops sharply against a multi-joint pull for the same muscle. Protect the range of motion; buying weight by shortening the arc defeats the point.

It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.

What you need

No equipment at all. The resistance is your own bodyweight, so you progress by changing leverage, range or tempo rather than by adding plates — and you can do it anywhere.

Difficulty

Listed at intermediate level. It assumes you already own the underlying pattern and can hold position under load — if the position breaks before the target muscle tires, drop back to a beginner variation until it does not.
