I have what you might call a pear-shaped body and I'm looking to tone it down and change my lifestyle. I'm already beginning to get unhealthy foods removed from my home and am making plans to exercise more often. Here's my exercise plan. I know everyone's different, but tell me if this sounds good to you: Crunches every morning and night. Four sets, 24 reps. Walking the dog a few times a week. I might join a gym to do a little more, but I have such a busy schedule that I need simple exercises like that. Just wanted to see if I was really doing as much as I should or not.
