I have a goal... lol... other than weight loss... that is the ability to run a mile... in under a half hour... with out walking... I have a nine week program for it that is for all activity levels... couch to 5 k (3 miles approx.) It helps you ease into running and it seems like it would work... I think I'm going to test it... scientific like... This way I don't see it as working out... i see it as an experiment! I'll start that when I'm able to get to the community gym with the treadmill or when the whether here isn't bad...
