Yes I do. According to the bmi chart I am obese. I weigh in at 250, drive trucks, and unload a trailer by hand every day delivering to orchard supply stores. It's enough to keep most people in shape lifting and pulling at least 100 pounds at a time. For me, it kept me in top shape. Outside of that, I hike, bike, run, and climb on weekends. So yeah, I suppose that could be the issue at hand. I am a very active person and I enjoy it immensely.
