Tuck Human Flag
The Tuck Human Flag is a sideways hold on stall bars with your knees drawn toward your chest. It challenges your side-abdominal strength and shoulder stability while shortening the leverage of a full human flag.
Higher injury risk. Read the safety notes before adding weight.
- Advanced
- Higher injury risk
- Rest 2 min
How to do it
- Stand sideways beside the stall bars.
- Grip separate rungs with your upper hand above your head and your lower hand near hip height.
- Press firmly through your lower arm.
- Pull through your upper arm against that pressure.
- Lift your feet sideways with your knees tucked toward your chest.
- Hold the tuck with your torso parallel to the floor.
- Lower your feet to the floor under control.
Form cues
- Keep elbows straight, not hyperextended.
- Stack your hips without rolling backward.
- Keep your lower shoulder away from your ear.
- Breathe steadily behind a firm brace.
Common mistakes
- Kicking into the holdUse a gradual lift rather than momentum to reach the position.
- Hips sagging below the shouldersBring your knees closer to your chest to shorten the lever enough to maintain a level torso.
- Loose fingertip gripWrap your fingers and thumbs fully around each rung for a secure grip.
Safety
Losing your grip or shoulder support can cause a sideways fall. Your arms bear substantial bodyweight, which can strain the shoulders or elbows if you enter abruptly or continue through fatigue.
- Check that the stall bars are firmly anchored and the rungs are dry.
- Place a stable landing mat beneath you with no obstacles nearby.
- Practice the push-pull support with your feet grounded before attempting an unsupported hold.
- End each attempt before your grip slips or your supporting arm starts to buckle.
If you have shoulder, elbow, or wrist pain or a history of shoulder instability, get advice from a physiotherapist before attempting this hold.
