BEST exercise seems to be walking. Just walk.... the thing about walking, assuming no walking disability, is that you have no excuse about equipment not working, or inability to get to the gym. Just walk you can walk in your house you can walk in your yard. You can walk at work, and you can walk at school. There was a guy in school that just walked up and down the stairs in the building and around the building. He must have lost about 100 lbs. I dont know what else he did, but he walked a lot and he dropped a lot of weight. A few years ago I committed to walking 10,000 steps a day. I really committed to it. I did not change much else and I lost about 50 lbs over about six months.
