do boxing help build mucles

[themusic]

i want to buid my upper body.will boxing increase the size of the mucles. i do punching for 1 hour daily and take some egg white.

just noticed you edited your post, with the egg white bit, the egg white is going to have no effect on your muscles unless your eating about 30 egg whites a day, to build lean muscle you want to be getting thru 1.5g protien to every lbs of your body weight.
