Has anyone ever done this? I had a max VO2 test done on me today and I recorded a VO2 max of 71ml/kg/min. I know Lance Armstrong isnt that far away from this number. I was very amazed. I hated having that **** tube straped to my mouth, heart rate monitor/ecg electrodes straped to my chest and the **** bp cuff. Overall it was the most intense exercise testing Ive EVER done.
