I have had the venue for 4 months now. I stopped using my Fitbit because it was showing my VO2 max as being 50 when that could not be true. I am 70 years old and do14, 000 plus steps a day and average 25 flights of stairs every day. I just did 20 flights stairs in 10 minutes and my fitness rating is 31. Get your act together, that cannot possibly be true.
