AC went down at my house for the last couple of days. It is 104 in San Antonio. It was a good excuse to go to the gym and get in some cardio. I ran on the treadmill not going below a 10 minute mile for about 4 miles that is the longest I have done on the treadmill if I calculated right I finished in about 38.00 minutes and it should have burned 600 calories according to my weight. Again I am on this site more for my fitness rather than bodybuilding but the tools here are unrivaled!
