Dragon flag

Log this in the tracker

A full-body lowering from shoulders to toes, the hardest classic ab movement.

What it is

Lying on a bench holding behind your head, you lift the whole body to vertical on the shoulders and lower it as one rigid line. It is an advanced anti-extension exercise.

Muscles worked

Primary: Core. Secondary: Obliques, Hip flexors, Lats.

How to perform it

  1. Lie on a bench and grip it firmly behind your head with both hands.
  2. Kick the legs up until your body is vertical, resting on the upper back only.
  3. Lower the whole body as one straight line, as slowly as you can control.
  4. Stop just above the bench and either reset or curl back up.

Common form faults

  • Piking at the hips on the way down. Squeeze the glutes to hold one line, and shorten the range you lower to.
  • Attempting the full version too early. Start tucked, then one leg extended, then straddled, then straight. It takes months, which is normal.

Programming

3 to 6 slow reps. Treat it as a skill: quality of the line matters more than the count.

Frequently asked questions

How long does a dragon flag take to learn?
Months for most people, working through tuck, single-leg and straddle versions. Rushing it usually means piking at the hips.
Do I need a bench?
You need something solid to hold behind your head that will not move. A bench, a heavy rack upright or a bed frame that does not slide can all work.
