The Negative Dragon Flag is an elite core exercise that emphasizes the eccentric phase to build extreme abdominal strength and total-body tension. By focusing on the controlled lowering of a rigid body, it maximizes time under tension for the rectus abdominis, lats, and hip stabilizers.

Setup
- Lie face-up on a flat bench and reach behind your head to firmly grip the edges of the bench or the support bar near your ears.
- Tuck your knees to your chest and then drive your legs straight up toward the ceiling.
- Lift your hips and lower back off the bench so your weight is supported only by your upper back and shoulders, creating a vertical line.
How to do it
- Inhale deeply and brace your core, glutes, and lats to lock your body into a straight, rigid 'pillar' from shoulders to toes.
- Slowly lower your entire body toward the bench as one unit, maintaining a controlled 3-5 second tempo.
- Exhale as you reach the lowest point you can maintain a straight line, stopping just before your lower back touches the bench.
- Drop your feet to the bench to reset, then return to the starting vertical position for the next repetition.
Form checklist
- Maintain a perfectly straight line from shoulders to toes; do not allow the hips to sag or 'pike'.
- Keep your elbows tucked in and pull hard on the bench to engage your lats for essential counter-leverage.
- Ensure your lower back does not arch as you approach the bottom of the movement.
- Focus on a slow, rhythmic descent rather than falling into the bottom position.
Pro tips
- Squeeze your glutes and quads as hard as possible to turn your body into a solid, unbending lever.
- Think about 'pushing' your feet away from your head to create maximum longitudinal tension throughout the anterior chain.
- The slower the descent, the more muscle fibers you recruit; aim for a 'stop-motion' feel during the hardest part of the arc.
Make it harder
- Pause for 2-3 seconds at the lowest point of the movement (just above the bench) before resetting.
- Perform the eccentric phase with ankle weights to increase the leverage challenge on the core.
Frequently asked
- What muscles does the negative dragon flag work?
- The negative dragon flag primarily targets the abs, lats, and obliques, and also works the erector spinae and serratus anterior as secondary muscles.
- What equipment do you need for the negative dragon flag?
- The negative dragon flag requires no equipment — just your body weight.
- Is the negative dragon flag good for beginners?
- The negative dragon flag is rated advanced. Build a base with simpler variations first, then progress to it with light load and strict form.
