I doubt u can have fully developed back, arms, chest, delts, quads, ham, glut, abs, calves, neck with only 2 dag/week...
If it was that easy all people could look great. But they really don't...1% of the people in the gym look great. and 0.1% out in everyday life look great. At the age 35+ very few poeple make it. I'm not talking gearheads, normal people doing it natural, the hard way.
Increased training volume make u better. There is no time for rest if u want the complete package! That's my experience.
