I've been working on getting back into shape. All I did was cut out alcohol and get off my butt and work out. Started about 3 months ago and could barely run one mile at a 10 minute/mile pace and now I'm up to 5 miles at a 7 minute/mile pace. So far I have lost about 20 pounds in those 3 months and it took me about 2 years to gain those 20 pounds.
