Dragon Flags: The Ultimate Core Exercise
The dragon flag is an advanced bodyweight core exercise popularized by Bruce Lee, where you lower and raise your entire body as a rigid plank while only your upper back and shoulders remain on the bench.
Proper Form
Lie on a bench and grip the edges behind your head with both hands for an anchor.
Contract your core and lift your entire body up until you are balanced on your upper back, body forming a straight line toward the ceiling.
Slowly lower your rigid body in a straight line, keeping only your upper back on the bench.
Lower until your body is just above the bench surface without touching, maintaining the straight line.
Reverse the motion by pulling your body back up to the vertical position using your abs.

Dragon Flag on GLP-1 Medications
Dragon flags are an elite-level core exercise that most GLP-1 patients should aspire to long-term rather than attempt early in their fitness journey. They require exceptional core strength, body control, and a favorable strength-to-weight ratio. As GLP-1 medication reduces body weight, the exercise becomes relatively easier, which can serve as an inspiring long-term goal. Patients should build a foundation through planks, leg raises, and ab rollouts for months before attempting even the tuck variation of the dragon flag.
Variations
- 1Tuck dragon flag — bend your knees to shorten the lever arm for beginners
- 2Single-leg dragon flag — extend one leg while keeping the other tucked
- 3Negative-only dragon flag — lower slowly and reset to the top, skipping the concentric
- 4Straddle dragon flag — spread legs apart to reduce the lever arm slightly
The Bruce Lee Legacy
Dragon flags are synonymous with Bruce Lee, who performed them as part of his legendary conditioning routine. Sylvester Stallone later popularized them in the Rocky IV training montage. Beyond their cinematic appeal, dragon flags are genuinely one of the most effective core exercises ever devised. They create an enormous lever arm that your abs must resist, producing extreme muscle activation throughout the entire rectus abdominis, obliques, and deep stabilizers simultaneously. Very few exercises match the total core demand of a properly executed dragon flag.
The Progression Ladder
No one should attempt a full dragon flag on day one. The progression takes months of dedicated training. Start with tuck dragon flags where your knees are bent tight to your chest, reducing the lever arm dramatically. Once you can perform 3 sets of 8 tuck dragon flags with control, extend one leg while keeping the other tucked. When single-leg dragon flags are manageable for 3 sets of 6 per leg, try the straddle variation. Finally, bring your legs together for the full dragon flag. Negative-only reps (lowering slowly, resetting at the top) are an excellent tool at every stage of this progression.
- Stage 1: Tuck dragon flags — 3 sets of 8-10 with slow tempo
- Stage 2: Single-leg dragon flags — 3 sets of 6-8 per leg
- Stage 3: Straddle dragon flags — 3 sets of 5-6
- Stage 4: Full dragon flags — start with 3 sets of 3-5 reps
Common Errors That Make Dragon Flags Dangerous
The most dangerous mistake is allowing your hips to bend (piking) rather than maintaining a straight body line. When you pike, the load concentrates on the lower back rather than distributing across the entire core. The second major error is attempting the concentric (lifting up) before you can control the eccentric (lowering down). Master the negative portion first — lower yourself over 5-8 seconds, then reset to the top position. Only attempt the full concentric when you can lower with perfect body position for 3 sets of 5.

Frequently Asked Questions
For someone with a solid base of core strength who can do hanging leg raises and ab rollouts, the progression from tuck to full dragon flags typically takes three to six months of consistent training. Starting from scratch with no core training background may take a year or longer.
Dragon flags are extremely demanding and train the core through anti-extension. However, they do not train rotation (like woodchops) or anti-rotation (like Pallof presses). A complete core program still benefits from exercises in all planes of motion, but dragon flags can serve as your primary sagittal-plane core exercise.
You need a sturdy anchor point. A flat bench with a solid base, a heavy barbell in a rack at low height, or even a sturdy pole can work. The anchor must be immovable — if it shifts during the exercise, you will fall. Some gyms have dedicated dragon flag stations.
Both are advanced core exercises that produce high levels of ab activation. Dragon flags emphasize anti-extension (resisting back arch) while hanging leg raises emphasize hip flexion against gravity. Dragon flags generally produce more total-body tension. Including both in your program covers different core functions.
