General Information
Dragon Flag is an advanced compound bodyweight exercise that primarily targets the core. Popularized by Bruce Lee, it involves lying on a bench, gripping behind the head, and raising the entire body into a vertical position before lowering it under strict control until nearly parallel with the bench. The movement demands exceptional abdominal strength and full-body tension.
What makes the Dragon Flag uniquely challenging is the extremely long lever arm. Unlike a Crunch or Sit-Up, the entire body from shoulders to toes acts as a single rigid unit, placing enormous anti-extension demands on the rectus abdominis. The only point of contact with the bench is the upper back and shoulders, which means the core must resist gravity across the full length of the body.
The exercise also requires significant isometric strength from the lats, triceps, and grip to anchor the upper body to the bench. Without a strong brace from these muscles, it is impossible to maintain the leverage needed to control the movement. This makes it a true full-body exercise despite its classification as a core movement.
Trainees should have a solid foundation in exercises like the Hanging Straight Leg Raise, Lying Leg Raise, and Plank before attempting Dragon Flags. Progressing through tucked and single-leg variations is the safest way to build up to the full movement.

Instructions
- Lie face-up on a flat bench and reach behind your head to grip the edges or the supports of the bench firmly.
- Pull your shoulder blades together and press your upper back into the bench. This is your anchor point and should not leave the bench at any time.
- Brace your core and squeeze your glutes, then raise your entire body upward until it is nearly vertical, balanced on your upper back.
- Keep your body in a perfectly straight line from shoulders to toes, avoiding any bend at the hips.
- Slowly lower your body toward the bench in a controlled manner, maintaining full-body rigidity.
- Lower until your body is just above the bench surface, roughly parallel to it, without letting your hips sag or touch down.
- Pause briefly at the bottom, then reverse the motion by contracting your abs to raise your body back to the vertical position.
- Repeat for the prescribed number of repetitions, maintaining the straight-body position throughout.
Common Mistakes
Injuries
Dragon Flag is a high risk exercise when performed with proper technique, and even more so when attempted without adequate preparation. The extreme leverage places very high forces on the lumbar spine, and any loss of the rigid body position can result in hyperextension of the lower back.
Trainees with any history of lower back injuries, herniated discs, or spinal issues should avoid this exercise entirely. Even healthy individuals should only attempt it after demonstrating proficiency in prerequisite exercises such as the Hanging Straight Leg Raise and Lying Leg Raise.
The grip and shoulder position also warrant caution. Gripping the bench behind the head places the shoulder in a vulnerable position, and losing grip mid-rep can result in an uncontrolled fall. Ensure the bench is stable and the gripping surface is secure before every set.
If you experience any lower back pain during the movement, stop immediately. Regress to tucked Dragon Flags or negative-only repetitions until you have built sufficient strength to maintain a rigid body line throughout the full range of motion.
Frequently Asked Questions
- Q: What are good progressions toward a full Dragon Flag?
Start with tucked Dragon Flags where the knees are bent, then progress to single-leg variations. Negative-only reps, where you only perform the lowering phase, are also an effective way to build the necessary eccentric strength.
- Q: Can I do Dragon Flags on the floor instead of a bench?
You can, but you will need a sturdy object to grip behind your head, such as a heavy piece of furniture or a pole. The bench provides a convenient gripping surface and a slight elevation that makes the movement easier to set up.
- Q: How many reps should an advanced trainee aim for?
Full Dragon Flags are extremely demanding. Sets of 3 to 8 controlled repetitions are sufficient for most advanced trainees. Quality of each rep far outweighs quantity.
- Q: Is the Dragon Flag better than the hanging leg raise for core development?
They train the core differently. The Dragon Flag emphasizes anti-extension strength across the full body, while the Hanging Straight Leg Raise focuses on hip flexion against gravity. Both are valuable and complement each other.
