If you are having difficulty obtaining a cycling VO2 Max Estimate, try riding a course where you can maintain a steady effort. You can also try using an indoor trainer.
Cycling activity must be 20 minutes in length or longer without stopping
Heart rate data from either a built-in optical heart rate sensor or from a chest strap
Heart rate must be elevated to at least 70% of your maximum heart rate for at least 20 minutes continuously
Yes have a chest hr strap. Works fine. Doing all the steps that are in that article. Just doesn’t update the vo2 screen on my iPhone app or online app.
