I hear so many weird things man....
Like some say, genetics determine your muslce density, so you wont get muscle density but you will get bigger...
other say you can increase your muscle density and but you can't get bigger...
some say you can alter the shape of the muscle... other say you can't do it....
How do you get more dense? well you gotta just increase the muscle size plus its muscle maturity ... how old are you? the bigger your muscle get, the deeper your cuts will look when you diet down... its like mountains.... the valley always seems deeper when the mountains around it are higher!!
