The leg raise dragon flag is an advanced body-weight core exercise popularized by Bruce Lee that challenges your entire midsection with a rigid, full-body plank held off a bench. By gripping a bench behind your head and raising your body in a straight line, you force the waist to resist extension under load — making it one of the most demanding core strength movements available without equipment.

How to do the Leg Raise Dragon Flag

  1. 1Lie flat on a sturdy bench and reach both hands back to grip the bench firmly beside your head, thumbs wrapped around the edge for a secure hold.
  2. 2Brace your core, squeeze your glutes, and press your upper back into the bench to create a stable shoulder anchor — this is your only contact point during the movement.
  3. 3Raise your legs and hips off the bench in one controlled motion, lifting until your entire body forms a straight line from shoulders to feet, perpendicular to the bench.
  4. 4Hold the top position briefly, maintaining a rigid plank — do not allow your hips to pike or your lower back to sag.
  5. 5Lower your body slowly and under control toward the bench, keeping the straight-line position throughout the descent.
  6. 6Stop just before your body touches the bench — hovering a few centimetres above it — to maintain tension in the core.
  7. 7Raise back up to the top position in a controlled manner to complete one rep.
  8. 8After your final rep, lower your body all the way to the bench and release the grip.

Form tips

  • Your upper back and shoulders are the only things that should contact the bench — think of your body as a single lever pivoting from that point.
  • Keep tension in your glutes and legs throughout; squeezing them helps maintain the rigid plank and prevents your hips from dropping.
  • Control the lowering phase — the eccentric portion is where most of the core stimulus occurs, so resist the urge to drop quickly.
  • Breathe out as you raise and breathe in as you lower, keeping your core braced throughout both phases.
  • If the full dragon flag is too demanding, start with a tuck position (knees bent to chest) and gradually extend your legs as strength improves.

Common mistakes

  • Allowing the hips to sag on the way down, which compresses the lumbar spine and eliminates the core challenge the exercise is designed to provide.
  • Piking at the hips instead of keeping a straight line from shoulders to feet, which reduces the difficulty and places stress on the hip flexors rather than the full core.
  • Using momentum to swing the legs up rather than lifting with a controlled, braced core — this bypasses the target muscles and increases injury risk.
  • Gripping the bench too loosely, which causes shoulder instability and makes it impossible to maintain the fixed pivot point the movement depends on.
  • Rushing the negative phase by dropping the body quickly, which wastes the most valuable part of the rep and increases the risk of a sudden load on the lumbar spine.

Frequently asked questions

What muscles does the dragon flag work?

The dragon flag primarily challenges the entire core musculature — including the rectus abdominis, obliques, and deep stabilizers of the waist — as well as the glutes and lower back, which must all work together to maintain a rigid straight-body position.

Is the leg raise dragon flag suitable for beginners?

No — it is an advanced exercise that requires substantial core strength and body control. Beginners should first develop a solid foundation with planks, leg raises, and hollow body holds before attempting it.

What equipment do I need for the dragon flag?

You only need a flat, sturdy bench that will not tip when you grip the end and apply force. No additional equipment is required.

How is the dragon flag different from a regular leg raise?

A regular leg raise keeps your upper body flat on the bench and lifts only the legs. The dragon flag raises your entire body as a rigid unit from the shoulders down, dramatically increasing the lever arm and the demand on the core.

How do I make the dragon flag easier while I build strength?

Start with the tuck dragon flag, keeping your knees bent throughout the movement to shorten the lever. As your core strength improves, gradually straighten your legs until you can perform the full version with control.
