You have
to go into it knowing just how far you're willing to go. You can't skip days,
forget to eat and then wonder why you're not gaining. I normally eat every 2
to 3 hours, eating small meals that fill me but not over full. You need protein
that's the key in muscle growth. The rule of thumb is double the protein to
your weight ratio. There are many supplements on the market, some work others
don't.
