yeah, thats a good article, it tells you what to do, however, it doesnt really say much about why that method is effective, but thats not what the article is suppose to do, because his got so many other articles covering that.
Waterbury has tons of full body workouts on that site, aswell as many cool methods of gaining strenght, like the 10x3 (10 sets, 3 reps), ive seen some GOOD gains with that, his become on of my favourite authors.
just make sure when you bulk that you dont do it the "traditional" way, with eating tons of food and gaining like 2lbs a week, because that will be mostly fat, do it slowly and controlled.
