Glad to be here

Hi everyone, I am a male in my mid-20's and just joined this site last night. While in college, I was a personal trainer and competed in several bodybuilding competitions. For several years, weightlifting and proper nutrition were the cornerstones of my life. However, after graduating college I moved away from home and got a job where I just sit in a cubicle all day. After being at work for 9 hours, I would find myself tired and started putting off going to the gym. I also just started getting more lazy in regards to nutrition and alot of times after work I would need a few drinks. And then of course after a few drinks, you feel like eating some greasy junk food. Anyway, its been several years now, and I feel like I have really let myself go. It's quite depressing to look at my old competition pictures and then look at myself in the mirror now. However, it also gives me hope that I can get back to where I was. The thing with me is that I know all the correct things to do in order to get in shape; its just a lack of willpower and not actually doing it when the time comes. I will often do good during the week and then go out to a bar on Friday and Saturday night and totally blow all the progress I made from Sunday through Thursday. Anyway, I'm ready to make a commitment to lose the weight now, and I think tracking all my meals and posting on these message boards will help keep me accountable. And if anyone has any questions regarding diet and exercies, I am more than happy to help. Like I said, I consider myself pretty knowledgeable on these subjects; the hard part is just doing it.
