No doubt, the mental aspect is the most difficult... in fact I failed last winter; spent the entire riding season to heavy, out of shape, tired and feeling pretty bad about it.
Everyone gets their motivation from different places. 2 years ago for me it was to be able to ride a couple of motos, full-on. This year it's that and the fact that when I see a picture of myself I can't believe what I see. I'm really not that over-weight person. I swear!
Do this. Get in a bathing suit. Have someone take a pitcure of you. Hang it on the wall so you have to see it everyday. In my case, that's all the motivation I need. :scream: .
Seriously, with me it's not sticking with it, so much as it is starting. Once I get going for a week, I'm good to go. Don't think of it as some short term thing you are putting yourself thru. Think in terms of long term changes to insure a healthier existance. And by healhier, I don't just mean something on a doctor can see by running test, I mean FEELING better. It's amazing how much what you eat and how much you exersize effects even your mental well being... at least in my case. Maybe it's just knowing I'm in control?
Many make the mistake of jumping in too deep right off the bat, looking for instant gratification, which leads quickly to burn-out. It's just not like that. Example, I started up last week by simply refusing to eat fast / junk food, getting my water intake up and eat my 6 a day. This week I started the cardio. Next week the lifting. 12 weeks from now I will have lost 25-35 pounds, increased lean mass and will fell great. I'll also be able to pull all that 32" gear and jeans out of the closet.
The BFL book is I think $13? Good investment. A lot of good inspirational stuff to keep you into it, a good portion of the book focuses on the mental game. It's a good buy.
Oh, and stay off the scale. The number is meaningless. Get yourself a tape and measure at several points. Re-measure every couple of weeks. Keep in mind, muscle is a lot heavier than fat, you may be doing really well and it not show up on the scale. Get a body fat test... anything, but stay off the evil scale.
