I am not anti- cardio. I believe it is tremendously misunderstood. If you want to compete in most sports, then you should be doing lots of it. If you want to look good naked then you probably shouldn't. When you do decide to do it, you should do it right. I get right down to the nitty gritty about aerobic vs anaerobic, heart rate zones, high intensity training and much more on this new episode.
