He's the first source I got into when I started (not all that long ago)
Seems like a lot of good information ( he has put a lot of effort into ways to work out at home/without much equipment) but a few things I dislike. He has no passion. His expectations for results are pitifully low and just inaccurate (5 lb a year!), at least for a beginner. Diet info is hardly ideal for muscle gain (that all that you need is the protein, and you will gain optimally regardless of other calories).
Obviously it does look like he practices what he preaches, and is in very good shape. But to be honest he was 190 lbs before ever picking up a weight (over 20 years ago) - he didn't really make that big of a transformation. His methods are ok for bodybuilding purposes and general fitness but not at all optimal for the former.
edit: this was a comment on his youtube video, shows exactly why people really shouldn't be listening to him.

@IbombYourAss I have the same body type. About 7 monthsï»¿ ago I was 6"1 and 140 lbs. Now I'm 145 lbs with no extra fat (I know thats still not by any means big, but it's a start). Just keep at it and eventually you'll put on muscle. And it sucks but some people like you and I just aren't genetically wired to put on tons of muscle.
