Cross: hips before hands

Power in the cross comes from the rear hip and foot, not from muscling the arm. When the hand leads the hip, the shot is arm-only and easy to time.

If you train alone, that sequence is easy to fake. The punch still lands on air; nothing tells you the hip never came with it.

Form Fighter looks for hip-before-hand timing, then runs a corrective set that cues the turn while you throw — hands-free so you can focus on the mechanic.
