I think the VO2 max calculator I used is broken or something. I took my resting heart rate 3 times and used the average, then put in my age and its got me down as having an 'Excellent' VO2 max. Since when did I go from flabby and unfit to excellent in anything to do with fitness?
Yet in another test that didn't include age or heart rate, that just went on what I percieved my speed at walking a mile would be, I was 'bleurgh'.
Another one that I have just tried has my fitness age as 70 years old (if I had done this 4 months ago would it have told me that I was dead and should get off the computer?) but my VO2 Max, adjusted for age was 35ml/kg/min which wasn't too bad for my general weight etc. I am going to bookmark that site and see if things change on a month by month basis.
