Tony,
You rock dude

. Don't worry about the weights you are moving; focus on your diet and regular exercise. Make sure you do your exercises with strict form. FORM IS EVERYTHING! The weight will come. I can tell you from first hand experience, you will be stronger now, than you were when you were 20. How do I know? See my siggy?? My best, absolute best competition deadlift when I was 21 was 455@181 lb body weight. Last weekend, I pulled the best d/l I ever have; this am when I did deads, I pulled 515, and attempted 545, which I never would have even tried until now. I weigh more now, certainly, but my strength is way more than when I was 20. I still have to drop at least 30 lbs of fat myself, and then focus on building muscle from there.
Life... happens. No need to say "no whining, excuses, or crying". I would suggest having the attitude that while there may be whining, excuses, and crying, those things won't get in the way of the goals you have. The fact is, you ARE going to the gym. That is more than most can say. On those days that you truly don't feel like going, go anyway... you'll feel better about yourself when you're done. The past is the past... so ya put on a little weight. Well, it happens. If you do the things you say you are going to do, the weight will come off, the demolition will occur, and the rebuilding will happen.
Best regards,
Dan
