Human flag: spot and fix your mistakes
In the human flag, SkillTrack checks whether your bottom arm stays straight. A bent bottom arm makes the hold much harder and has its own cause. SkillTrack is a web app that analyzes your phone video on your device and tells you whether you have this mistake.
How do I spot a mistake in my human flag?
A video of yourself shows whether something is off:
- Bottom arm bent: the arm that pushes the pole away gives in (at every stage).
Why is my bottom arm bent in the human flag?
You still lack straight-arm strength. Lock your elbow, push the pole away.
These exercises help against a bent bottom arm
- Bottom-arm push hold: practice the feeling in the bottom arm without lifting your whole body.
- Push-up Plus: strengthens the muscle that keeps the bottom arm long and strong.
- Wall handstand lean: your arm is overhead like the bottom arm in the flag.
How does SkillTrack check your human flag?
You film yourself with your phone from the front, beside the pole or pick an existing video. The analysis runs on your device: the video and body points never leave it.
SkillTrack detects the angle you filmed from and only checks mistakes that can be measured from that angle. If the angle doesn't fit, the app rejects the recording instead of judging wrongly.
You get the finding in one sentence, the reason behind it, and matching exercises.
What comes next?
In SkillTrack, the path to the human flag has four stages: tuck, one leg, straddle and full.
