Dragon Flag
An extremely demanding full-body core exercise made famous by Bruce Lee, requiring significant total-body strength and control.
Lie on a bench, gripping it behind your head for stability. Begin by lifting your entire body to a vertical position, supported only by your upper back and shoulders.
Lower your body as one rigid unit. Keep your legs, hips, and torso in a straight line, resisting the pull of gravity as you lower. Stop before your hips touch the bench. Maintain tension and control rather than resting at the bottom.
Raise back to vertical with control. Reverse the movement using your entire core, not momentum.
Bending at the hips during the lower. If your hips bend, you've lost the rigid body line that makes this exercise valuable — this is the most common failure point.
Why it matters
The dragon flag asks the core to support and control your entire body weight as you lower from a vertical position down to nearly horizontal, holding everything except your upper back rigid and off the bench. It's one of the most demanding core exercises in common use and should be approached as a long-term goal, not an early addition to a routine.
How to do it
- Lie on a bench, gripping it behind your head for stability. Begin by lifting your entire body to a vertical position, supported only by your upper back and shoulders.
- Lower your body as one rigid unit. Keep your legs, hips, and torso in a straight line, resisting the pull of gravity as you lower.
- Stop before your hips touch the bench. Maintain tension and control rather than resting at the bottom.
- Raise back to vertical with control. Reverse the movement using your entire core, not momentum.
Common mistakes
- Bending at the hips during the lower. If your hips bend, you've lost the rigid body line that makes this exercise valuable — this is the most common failure point.
- Attempting full dragon flags before adequate strength is built. Bent-knee dragon flags and other progressions are appropriate and necessary stepping stones.
- Rushing the lowering phase. Control through the entire range, especially the lowering portion, is where most of the strength benefit comes from.
- Using a bench that isn't secure or sturdy. Given the demands of this exercise, a stable, secure surface is a genuine safety consideration.
Sets & reps by level
Not applicable — build foundational core strength with other exercises first.
Begin with bent-knee dragon flags for 3 sets of 4–6 reps, focusing on the rigid body line rather than full extension.
3–4 sets of 4–8 reps with straight legs once strength allows, full control through the entire range.
