This year I have resolved to exercise more. I had been on a calisthenics program that was working well for me (I was doing honest to God push-ups for the first time in my life) but I had let it slide for all the typical excuses. Yesterday I started back up again and today I have the anticipated soreness.
Something I did not do was resolve to diet. I won't be going crazy eating whatever, but I an not making special pains to go beyond moderation. The way I see it, I want to get into shape to better enjoy life.
The short way off putting it: I would rather force myself to do something unpleasant for an hour a day than to keep myself from NOT doing something all day.
