Re: Sparring and finding range
what i done when i first started out (and i still do but not as much) was shadowbox, shadowbox, shadowbox. you can work on breathing, footwork, technique, head movement while doing this.
I too had the same problem, i would be throwing punches and they would be stopping 6 inches short of the other guy, he could of stood there and not get hit! I found out it was down to footwork & technique - stepping with jab, rotating hips into shots etc.
if a guy is coming in steaming hundreds of punches at you, then, chances are hes coming at you in a straight line, try not to back away as someone mentioned, maybe take 2 steps back and one to the side, this will maybe create angles for you.
all the best
