Polar's A5 combines exercise guidance with valuable feedback about your workout. Polars Self Walk Test, a built-in walking test, tells how fit you are and helps set up an exercise program. The A5's Zone Pointer keeps you in a specified target zone, and the OwnCal calorie counter helps manage your weight-loss program. The A5 also tells how efficient your workout was by tracking time in a heart-rate zone and total calories expended. Using an A5 is like having a personal trainer attached to your wrist!
