that kind of muscle mass is not something all females want. They want some muscle and minimal body fat.
Men dont have to do 'much' to get in decent shape either.
as someone who i know frequents the gym
do you realize how hard it is to put on quality mass

2-4lbs a month isnt jack shyt, hell if i wanted to be kooked's size it would take me a solid year before i got there
women will never have to worry about shyt like that
