Fastest and best way to step forward and throw the straight right?

[AlexKid]

So your opponent is out of reach you need to get a bit closer to hit him, what do YOU do with your feet?


e.g. some people might lean in a bit and by lean I mean slip.

some might take a step with their front foot only to get a little closer

some might push off their rear foot step fowards bring their rear foot up then throw the cross

etc etc etc

whats the best way (excluding stepping in with the jab 1st) and whats the fastest way to close that distance?
