Hey James. I totally feel what you're going through right now. I just returned from Spring Break, and I felt like a cow the entire time (it doesn't help when the people you go on vacation with only weigh 100 lbs). I've been working out a lot lately, but I think my eating habits are getting the best of me. So, I started a new plan where I am doing cardio 3 times a week and I will weight train 2 times a week. The weekends are game for whatever workout I want, just as long as I do something.
Currently, I have a decent amount of muscle. I realize that muscle weighs more than fat, but I want to tone up the fatty areas by focusing on cardio, and then I'll tighten them with weight training. If I stick to it, I will be on this plan for the next 6 weeks, after which I will change up the routine. I'm not looking to lose 50 pounds...but 20 pounds sure would make me a happy person. No more sweets for me...unless they come from a box labeled Slim Fast or Healthy Choice.
Good luck (we can be each other's moral support).
