For two reasons I think. One, it 'prevents' us from being bored while in the bathroom and two, we like to read about people who exercise. I guess.
This morning I read a short article with the lesson that if you really want to lose weight during a walking program, you absolutely need to step up the pace to 4 miles per hour. So...Speed up.
The second article I read said that some researchers have found that increased exercise can increase your appetite so much that you begin to inhale too many calories and thus you slowly gain weight.... From exercising. Their answer is to slow down your exercising you fool. It will cut your appetite and thus your weight gain.
This points out why education is such a wonderful thing. If I hadn't been able to read at the rate I do, I might have read just the first article. As a result I might have accidentally started an exercise program. And gained more weight. And besides that...I hadn't even consulted my Doctor before starting this alleged exercise program.
"Uh...Doc...Hi this is Cliff, my magazine says to consult a physician before starting any exercise program and well, I'm thinking about doing a sit-up so I need to schedule an appointment."
