VO2 Max, FTP and all that stuff
Indoor time and back on Zwift. I am a 69 yr old middle of pack recreational rider. 4-5000 miles a year.
Zwift tells me that my VO2 Max is 36, which charts say is Good-Excellent for my age and weight (142 lbs)
And my tested FTP is 151 (better than last time!) is listed as "Untrained" or beginner. That was discouraging!
Am I fit or out of shape?
