it really depends on your begining physique which will clue you in on how to train. are you:
a)ectomorphic(thin/ bony)
b)mesomorphic(naturally strong and muscular)
c) endomorphic(strong but with a thich layer of fat preventing any natural muscular definition)
???
that what i was getting at, genetics play ahuge part in gaining initial mass. your bodys natural response to training can b different from others so u need to experiment with a wide range of liftas to get the most out of the fibers, but the sets/reps is pretty standard for ectomorphs @ 8-15
if youlift the heaviest wt you can, you'll use the most fibres...that means squats and deads are the way to go for overall mass, not multiple exercises for each muscle as the wt used will decrease from fatigue for every successive exercise that's performed
while deads do use more muscle groups they dont use the maximum amount of fibers you could recruit if you were doing an "isolation" exercise like rows or flyes or curls. it may take longer but youll have better preportions
You might, but longer isn't always better. You're then taxing the Lungs, Heart, CNS, etc etc for longer, and possibly beyond the point you need to go to get max benefit.
that is true but it would be silly to try that with every muscle...that's where we train differently...i train to get stronger and you train to get bigger
