The Norwegian University of Science and Technology has come up with an easy way to measure what they call your fitness age – without having to exhaust yourself on a treadmill (with the same result). They have put the calculator here.
For me, the vital statistics are:
How often do you exercise? Almost every day.
How long is your workout each time? 30 minutes or more.
How hard do your train? I go all out
What does your waistline measure in cm? 80
What is your resting pulse (per minute)? 46
Estimated fitness age: under 20!
