Quick question, but is this "friend" really you, since all you ever post are "how's this routine"-type threads? Just wondering. Regardless, my two cents...
Some more details would be nice, like exercises, sets, reps, and your friend's height, weight, and general fat level.
Well, what's his goal, to gain muscle or to cut fat? Did his bodybuilder friend give him any nutrition advice too?
At this level of non-development (no offense. Everyone was a beginner), I'd definitely go upper/lower or full body. There are tons of good programs in the archives. Almost any one of them will be fine if he's consistent.
The sooner he fixes this, the better.
How long has he been doing his current routine? Is he not "happy" with the results?
