How to learn the dragon flag: Bruce Lee's favourite core exercise
Three stages to the dragon flag: hollow hold, negative variation, full skill. Brutal core development straight from the Strive Up skill tree.
Contents
The dragon flag is probably the most famous core exercise in the world – made famous by Bruce Lee. You lie on a bench, hold on with your hands, lift your entire body and lower it slowly under control. Only your shoulders and upper back stay in contact with the bench.
What makes the dragon flag special
The dragon flag is much more than a sit-up on steroids. It is a full-body static tension pattern that trains the entire core – rectus and obliques, hip flexors, lower back – as one unit. If you can do a dragon flag, you have a core that is ready for the front lever, planche and muscle up.
Prerequisites
- A clean hollow hold – at least one minute.
- Hanging leg raises (10 clean reps).
- A stable bench with something solid to grip (bar or bench edge).
Your path to the dragon flag
Your path to the dragon flag
Bruce Lee's favourite core exercise: from the hollow hold via the negative variation to the full dragon flag.
The stages explained
1. Hollow hold (1:00)
The static foundation. Lying on your back, legs and shoulders slightly lifted, navel drawn towards the spine. If you can't hold this for a minute, you can't hold a dragon flag.
2. Dragon flag (negative)
The lowering phase only: from the vertical position (legs up), lower slowly and under control until your legs almost touch the floor, then use your hips to get back to the start. Five to eight seconds of negative per rep.
3. Full dragon flag (5 reps)
Lifting and lowering, both under your own power. The body stays rigid like a plank with only the shoulders and upper back touching the bench. Five clean reps is the Strive Up target.
Common mistakes
- Hips folding: the body has to stay in a straight line. If the hips fold, it's a leg raise, not a dragon flag.
- Arched lower back: working with an overextended spine dodges the core work. Actively pull the navel towards the spine.
- Lowering too fast: tempo is everything. Four to six seconds of negative is mandatory.
- Swinging into the rep: every rep starts cleanly from the start position. No momentum.
Training plan
Frequency: 2 × per week, easy to combine with a push or pull day
Volume: 4 sets at your current stage + 3 × 30s hollow hold as a finisher
Progression: once you manage 4 × 5 negatives with a 6-second lower, try the full lift.
