Dragon Flag

I used to treat core work as the bit at the end of a session. Now I think of it as the connective tissue of every skill: the hollow body in a handstand, the straight line in a lever, the compression in a press. The chart has several core families; here’s where I am on the main ones.

• Ab wheel: up to standing negatives. Goal: the full standing rollout.
• Dragon flag: full dragon flag done; weighted is the next step.
• Hanging leg raises: through windshield wipers and ankle-weighted toes-to-bar.
• Human flag: the two-arm elbow lever is in; the tuck flag and straddle flag are goals.
• Elbow lever: two-arm on the floor and rings; one-arm straddle is the goal.

Anti-extension: ab wheel and dragon flag

Both train the body to resist arching under a long lever, which is exactly what a front lever, planche and handstand need.

• Ab wheel cues: ribs down, posterior pelvic tilt, and roll out only as far as you can keep the lower back flat. Standing negatives first, then partial returns.
• Dragon flag cues: shoulders on the bench, body straight from shoulders to toes, lower slowly. Bend at the hips and it’s a leg raise.

Compression: hanging leg raises

Toes-to-bar with straight legs, then windshield wipers for rotation. They feed the L-sit and V-sit; see L-sit and V-sit.

The flag

The human flag is mostly lats and obliques, with a big shoulder component. I’m treating it as a lever problem: tuck, then advanced tuck, then straddle, like the front lever.

Programming

• Two core exercises per session, one anti-extension and one compression or rotation, two or three sets each.
• Keep the core engaged in every other exercise too. Ring rollouts and hollow holds are excellent.
• Rotate the flag and elbow levers in as skill work when they’re a focus, not every week.

Common mistakes

• Range before control: rolling out further than you can return from.
• Arching in dragon flags and rollouts. It’s the opposite of the point.
• Endless crunches. The core’s job in calisthenics is mostly to stop movement, not create it.
