I like a number of things about my Polar F11, but probably my most favorite feature is the quick five-minute fitness test, which allows you to establish your base line fitness. Let’s face it; most of us think we’re in better shape when we first embark on a new fitness program that we actually are.
The Polar F11 heart rate monitor watch allows you to design your own heart rate based fitness program from inputting the information derived from this short test five minute test into its popular Keeps U Fit program.
