I started a diet/workout routine about 3 weeks ago. So far I've gone from 255 pounds to 240. Weight has been a consistent issue for me in my life, in college I managed to lose 45 pounds from 215 down to 170, which is where I want to get, then start getting into weight training. Since then I let myself go after a slew of family tragedies and a horrendously bad break up a few years ago.
My schedule at work has a built in 2 and a half hour break, which I think will make it easier to maintain a workout routine once I get down to a weight I'm comfortable with. So far, it's 99% cardio, and almost all of that is treadmill time.
