nawchem,
You can do it. I understand how difficult it can be to get that first motivation up. About this time last year I was in so much pain and undergoing medical treatments. When things finally got bad enough I agreed to a surgery I had been putting off for over 5 years. By that time I was only able to sit, stand, or walk for about 5 minutes max. I spent most of my time lying on my side with my knee bend (pregnancy style). Once I had the surgery I had to spend 6 weeks recuperating. All during recuperation period I kept telling myself that as soon as I got the go ahead I'd get up and workout. Well it wasn't that easy. I had the thought but not the motivation.
Here's how I was finally able to approach it. In very small steps. 5 minutes on the treadmill. I promised myself just 5 minutes a day. I marked on the calendar the start day and made a special mark at the 1 week point and in big letters wrote 10. That was the day I promised myself to start 10 minutes a day.
One thing that happens is once you start it is easy to keep going. Tell yourself that all you have to do is start and your motor will kick in and do the mental work for you. Once you're up to 10 minutes you won't believe how good it starts to feel. Just do it. Remember it is only the starting it that takes a little work. I began by walking first thing in the morning when I was less likely to talk myself out of it and before my brain was awake enough to put up too much of a fight.
Once it becomes a part of your regular schedule it becomes habit ... just like brushing your teeth or going to your computer. All you have to do is take that first step and the rest follow almost on their own. It's like magic.
If you have something to do while walking (I listen to music or talk radio) it will make the time go in a blink and you'll hardly realize that you're "working".
And don't forget why you are doing it. You are doing it FOR YOU. Because you're worth it <insert Loreal commercial here>. You'll feel and look better and it will be good for you mentally (great to elevate mood and relieve stress) and physically. Do it because you really care about yourself/ You deserve it.
