Coordinate your punch with back foot landing, or with leading foot landing?

[drop bear]

Leading foot landing include

- heel landing, and
- toes landing.

He coordinate his punch with his toes landing. When he lands his heel, his punch hasn't finished yet. When he lands his toes, his punch has full extension.

Please notice his

- right foot toes from up to down.
- left heel from down to off the ground.

This guy has good body coordination do you think?

Yeah. He even halts his rush to do an evasive duck and weave which is quite impressive.
