Hook technique checks you can see on camera
A useful hook review on video focuses on a bent-arm shape, a short screen-plane arc, and a high opposite hand — not whether the shot would land. Form Fighter can watch hooks in standard 2D live practice and grade a clear side-on upload. Enhanced movement review may apply when eligible. This page is a checklist, not a fight prediction.
What this strike is
The hook is a short arc punch. On camera, the elbow should stay behind the fist rather than leading into a slap.
Hooks fail on film in two common ways: the arm straightens into a slap, or the opposite hand drops while the hook is out.
Keep reps short and slow until the shape holds. Speed without shape just grooves a wider miss.
How to film for a useful read
- Angle that shows the punching arm’s bend — often slight side-on
- Full upper body and head in frame
- Slow hooks first so the arc is readable
Visible-motion checklist
- Punching arm holds a bent-hook shape rather than a straight punch
- Arc stays short on the screen plane
- Opposite hand stays near the face through the throw
- Both hands recover to the cheeks after the arc
Common mistakes
- Elbow leading the fist — slap instead of hook
- Huge wind-up that lifts the chin
- Dropping the opposite hand
- No return after the arc
Eight slow hooks, shape first
Throw 8 lead hooks slowly. Freeze for a beat at the bent shape, then return both hands home.
Visible success criterion: On film, the elbow does not lead the fist and the opposite hand stays up.
What a phone camera can show
- Whether the punching arm holds a bent-hook shape
- Whether the opposite hand stays near the face if visible
- Whether the arc looks short vs wildly looping
What it cannot tell you
- Contact force or how the hook would land
- Whether liver or jaw would be open
- Exact rotational power
Safety and limits
Hooks load the shoulder and lead side. Start slow. Stop if something hurts. Not injury-prevention advice.
Form Fighter’s role
Standard 2D live and upload can watch a clear hook. Enhanced movement review may apply on eligible supported sessions.
Can I upload hooks for review?
Yes. Clear side-on hooks can receive standard 2D upload feedback. Enhanced movement review may apply when that session is eligible.
