This week Michael sits down with Stephanie Sullivan, exercise physiologist at The Endurance Edge, to chat about (and simplify) VO2 Max testing, metabolic testing, lactate threshold, anaerobic threshold, and field testing (like FTP tests) and what these things tell an athlete and how they can apply them. If you're an athlete wondering if you should invest in VO2 max and metabolic testing, you won't want to miss this one.
