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.
