Thanksgiving is soon and I just finished making a couple pies. One pecan and one cranberry(secret family recipe). Anyways I am going to post another quote I heard from Art Devany. It was something along the lines of "exercise is not meant to burn calories. Exercise is meant to fundamentally change your metabolism." "Exercise creates physiologic headroom." I like the fist one because so many people are worried about burning off calories. They eat a slice of cheesecake and follow it with a comment like, "guess I'll be on the elliptical for an extra 30 minutes tomorrow!" Proper exercise stimulates the release of hormones that increase lean muscle mass and burn fat. Sprinting, lifting heavy weights and walking/light running constitute proper exercise. If your diet is right that is all you need. 3-4 sessions of sprints and weightlifting with some slow walking on the side. Sprinting increases endurance as well as it trains the anaerobic and aerobic systems, see tabata and wingate sprints. See CrossFit Endurance for more on that.
I'm not sure what the point is of this post is other that TRAIN SMART. It is quickly becoming common knowledge that it is better to go real fast and real slow and stay out of the real medium place when it comes to fitness.
