Well done Larry! That takes some dedication.
Though it's mandatory I exercise for work, I go mountain biking every Saturday for 3 hours (about 10 miles) on hilly terrain. I also go to a free spin class at the local gym once a week. I've also changed what I eat to cut down on the junk I consume; minimize soda and typical desserts (cake, ice cream, doughnuts), drink more water, eat healthy snacks; nuts, jerky, etc. In November I was at 215, I'm now at 195 and holding strong.
