There many routines as many have directed you to in this thread and Chad Waterburys routines are excellent; however, no one routine is good for everyone and you can and should read about the various routines and then make an educated decision. I just wanted to make you aware of the current routine that I have been doing since it seemed to fit in with your goals of gaining mass while keeping the waistline in check.
I started out the routine at 220 pounds,6'3", 36 inch jeans and 35 years old. Twenty pounds later my waistline has not grown a millimeter but some of my lifts have grown.
In this six month "idiot" routine that I have been doing, weighted dips have gone from bodyweight(220)+ 45lbs to bodyweight(240) + 90lbs; full squats from 185lbs to 250lbs, dumbbell bench from 60lbs per arm to 115lbs per arm and deadlift from 225lbs to 350lbs.
But according to some this is a useless "idiot" routine. If you want to be an "idiot" though give it a try.
Good Luck with your goals.
