Yep! It was on... hmm, believe the machine brand is Life Fitness. One of the options on the display panel, besides Cardio, Fat Burn, etc, is Fitness Test. It sets itself up for 5 minutes at a speed you choose (2.0-4.5 mph I think is the range), then it measures your heart rate as you walk or jog. It ramps itself up too, into a little hill. I pick 3.0 mph because right now I'm a wuss heh!
I don't know what the number range is, though higher numbers are better! I test myself every so often to see if I'm making progress
Last time I did it in February, I was at 21/Poor, now I'm at 24/Poor. I know 25 is in the Below Average range since I saw that a while back when I was going more regularly. Soon I'll get to that, then Average then Above Average then maybe HOT MAMA!
