Human Flag

Also known as: Human Flag Hold

Hold your body horizontal beside a vertical support by gripping it with both hands and keeping a straight line from head to feet, using the obliques and broader core to maintain the position.

How to do the Human Flag#

  1. Grip a sturdy vertical support with one hand above the other—one palm facing down and the other facing up—and establish a firm hold.
  2. Engage your shoulders and brace your core so your torso is stable before initiating the lift.
  3. Drive your legs away from the support and lift your body until it is roughly horizontal and fully extended.
  4. Keep your hips level and core contracted to maintain a straight line from head to heels for the chosen duration.
  5. Lower your legs under control and release the grip one hand at a time to come down safely.
