Well, I read the 1st referenced link. OK, I'm not going to jump on it like Yoda (guest) did, but he did bring up some interesting points.The link is a split, and IMHO, you get more bang for the buck for "leaning" if you go full body. The program referenced supposedly has you going for strength, with a 5X5, and a 5X5 will definately give you strength, if you concentarte and do it right, but I don't see it contributing that much to fat loss. A version of this, done full body, with short rests, will work. I've seen it and done it. It's based on Korte's 3X3. (look it up over in the archives at Deepsquatter.com). Kortes is basically squat, DL, BP done for 5-8 sets each, 5-8 reps, starting out at 65%1RM. The first 4 weeks go up gradually.After that it slows down and becomes a strength program, but everyone I've talked to that tried it started shedding lbs when using these exercises circuit fashion with short rest breaks. Other spinoffs of this are DL, dip, chin done circuit, for 3 rounds, of 15, AMRAP, AMRAP, and squat, , press, row. Any of these will give you aesthtics when combined with a healthy diet geared to fat loss. When going for fat loss, or leaning, get the most muscle amount you can working, and you can only do that with the large muscle groups, and exercises geared towards them. At this point, forget the isolation stuff. All the back pulling movements hit the biceps, quite hard, and all the shoulder/chest stuff hits the triceps quite hard. After you lean out, then fine, go for some isolation and splitting.
