I'm just starting to get back in shape and I think it would be fun to have reliable numbers so I can see my progress after one year.
Right now I'm using the 220-age formula for my max heart rate. This means 190 for me. If I pedal really hard on the trained and get a higher numder than 190 should I use this as a max HR?
How can you find out your VO2 max? Are there places where they test you for this for a reasonable fee?
How accurate is the calories display on polar computers?
