Dragon Flag
Made famous by Bruce Lee, the dragon flag is one of the toughest bodyweight tests of core strength there is. You anchor at the shoulders and lower a straight, braced body toward the bench while the abs fight to stop the spine from extending. It builds ferocious rectus and oblique strength, but only attempt it once you own strict hollow holds and hanging leg raises.

How to do it
- 1
Lie on a flat bench and grip the edge or a post behind your head with both hands.
- 2
Brace hard and lift your legs and hips until your body is stacked nearly vertical over your shoulders.
- 3
Keep your entire body straight and rigid from ankles to shoulders.
- 4
Inhale and lower the straight body slowly, resisting the urge to let the hips sag.
- 5
Stop just before your heels touch down while keeping the low back from arching.
- 6
Exhale and pull the body back up in one rigid piece, then repeat.
Tips
- Squeeze your glutes and quads so the whole body moves as a single plank, not in segments.
- If the full lever is too hard, bend the knees to shorten the lever and progress from there.
- Never let the low back arch off tension; stop the descent the moment you feel it give.
Variations
Common mistakes
- The hips break first on the way down, so the legs lower while the torso stays up and the movement turns into a slow leg raise with the abs half out of it.
- Anchoring with the hands on the bench edge beside your ears, rather than on something solid behind your head, lets the whole body slide up the bench on every rep.
- Weight ends up on the neck instead of on the shoulder blades, which is uncomfortable and genuinely risky under a load this size, so shift your contact point down before you lift.
- Most people go to full extension long before they can hold it, then bounce off the bottom to get back up, and the bounce is where the low back gets whipped into extension.
- Breath gets held for the whole rep, and since the descent takes five or six seconds you arrive at the hardest part with no air and a collapsing brace.
Frequently asked
- How many dragon flags should you do when you are new to the exercise?
- Once you can lower with straight legs at all, 3 to 5 sets of 3 to 5 reps with a full minute of rest is the right dose, placed at the start of your core work while you are fresh. If you cannot complete one clean rep, do not grind through it: spend a few weeks on tuck flags and slow negatives, then retest. Going past six reps rarely helps here; slow the descent or add a pause instead.
- How do I make the dragon flag easier or harder?
- Easier: bend both knees into a tuck, or extend one leg and keep the other tucked, which shortens the lever without changing the position. Slow negatives with a knee-bent reset are the most useful regression of all. Harder: pause two or three seconds a hand's width above the bench, stretch the descent to eight seconds, or set the bench on a slight decline so the anchor sits higher than your hips. Ankle weights come last, once five or six slow, clean reps feel routine.
- What is the dragon flag actually training?
- It is anti-extension strength, the abs holding ribs and pelvis together while your body weight tries to pull the spine into an arch, and it transfers to front levers, gymnastics work and staying rigid under load. It is a poor choice for beginners and for anyone with a low-back or shoulder problem, since the whole load lands on the abs and shoulders at once and the failure mode is the spine snapping into extension. Build hollow holds and hanging leg raises first.
