# Human Flag Progression Tree (L6 – L10)

> The Human Flag is a lateral coronal-plane isometric hold where the athlete suspends their body horizontally perpendicular to a vertical pole or stall bars. The bottom arm acts as a straight-arm overhead press pillar while the top arm performs a straight-arm lateral pull, bridged by intense external and internal oblique and gluteus medius tension. Athletes should achieve 12 strict Pull-Ups, 10 HSPUs, and a 45-second Side Plank before training tucked lateral flag holds.

- Apparatus: Vertical pole, Stall bars
- Target Muscles: External & Internal Obliques, Quadratus Lumborum, Latissimus Dorsi (Top Arm), Deltoids & Serratus Anterior (Bottom Arm), Gluteus Medius

## Biomechanical Overview
The bottom arm bears compressive pushing load and requires strong scapular elevation/protraction to avoid shoulder impingement, while the top arm bears tensile pulling load.

## Progression Stages & Readiness Gates
| Stage | Skill Node | OG Level | Logging Type | Leverage | Readiness Gate | Mastery Standard |

## Frequently Asked Questions
### Which grip is strongest for the bottom hand in a Human Flag?
On a vertical pole, a supinated grip (thumb pointing down, palm facing the athlete) on the bottom hand allows external shoulder rotation and locks the elbow cleanly into pushing alignment.
