I am still breathing, but barely! I tried out this class that is like P90X and Insanity with a Beach Body Coach and Physical Therapist Tom Barbata. I have never experienced anything like it! I might make it a week without dying, but at this higher elevation I am still panting and coughing! It is hard enough getting up and driving around the corner at 5:30 a.m., but the burpees, push-ups, mountain climbers, boot camp workout, etc. are enough to wonder what I got myself into! I can't believe I survived!
