I am two weeks into my mission of getting back in shape. Since I will be 50 in a little less than two years, I have adopted as my motto "Fit by 50!"
I am taking a two-part approach to this:
1) making careful food choices, balance portions and types of food.
2) exercise. My husband and I are working together to do Leslie Sansone's Walk Away the Pounds. The basic program is a 6-week program, but we are doing each week twice to make it more feasible. Her program is a low-impact aerobic program, based on simple walking movements with arm movements added, and eventually resistance exercises added as well. Leslie is upbeat and easy to follow, so we enjoy her so far.
We just finished our 2nd week, and found the two-mile Saturday workout to be quite a bit easier than we expected. Our first week, we actually walked two miles on Saturday since it was a nice day, but I think the combination of movements on the dvd was a better workout and not so tiring because of the variety.
On the other hand, you can't stop and talk to neighbors while you are in front of the TV, so it's a tradeoff.
