Guide

Cross technique checks you can see on camera

A useful cross review on video focuses on a straight screen-plane path and a clean recovery to guard — not measured power. When the arm races ahead of any visible turn, the shot looks arm-only. Form Fighter can watch a cross in standard 2D live practice and grade a clear upload. Enhanced movement review may apply when eligible. This guide is mechanics, not a guaranteed automated grade.

What this strike is

The cross is the straight rear-hand punch. On film, judge the path and the reset. Do not treat “perfect hip yaw” as something a phone verified.

Solo crosses often look fine in a mirror and still loop or leave you open on camera. Path and recovery are the honest checks.

If you want to feel more rear-side involvement, treat that as an instruction cue — separate from what Form Fighter can measure.

How to film for a useful read

  • Side-on or slight angle so the rear hand’s path is visible
  • Feet in frame through the throw and recovery
  • Isolated crosses before combining with jabs

Visible-motion checklist

  • Fist travels on a straight screen-plane path, not a wide loop
  • Chin stays down behind the shoulder line when visible
  • Both hands recover near the face before the next shot
  • Stance looks usable after the throw — not fallen off the line

Common mistakes

  • Arm-only: fist arrives while the body stays square and still
  • Wide looping path that reads as a slow hook on camera
  • Chin lifting to “see” the finish
  • No return — hand hangs out after the shot

Eight crosses, home to guard

Throw 8 crosses at a controlled pace. After each, both hands must be near the face before the next rep.

Visible success criterion: On film, the path stays relatively straight and recovery is visible every rep.

What a phone camera can show

  • Whether the rear hand travels on a straight vs looping path
  • Whether hands return toward the face
  • Limited visible turn of the torso/hips as a quality-gated proxy — not exact yaw

What it cannot tell you

  • Contact force or punch power
  • Exact 3D hip yaw or heel-pivot angle
  • Weight transfer through the floor

Safety and limits

Warm up before hard crosses. Stop if the shoulder or back complains. This is not injury-prevention advice.

Form Fighter’s role

Standard 2D live and upload feedback can watch a clear cross. Enhanced movement review may apply on eligible supported sessions. Instruction cues about “hips first” are not the same as a measured hip yaw.

Can Form Fighter measure my cross power?

No. It can review visible path and recovery. Power and impact are outside phone-camera measurement.
