after week 3 I wanted to fck even the fat girls at the gym, or anywhere else I saw them. by week four you should be cuffin the dummy a couple of times a day. as for strength and size gains, be patient boys, it's not a miracle drug, well not completely. it's like cfm said, you see yourself everyday, so your first compliment will probably come from someone else. the strength gains tend to sneak up on you, when you aren't expecting it, you'll pull off a few more reps with a weight you may struggle with normally. that's a great feeling, but you gotta be patient.
