When I was taking aerobics classes at my health club, the instructor would always have us check our pulse to see where it was and to match it with the chart hanging on the wall. Mine was always off the chart. I never really knew what we were doing or if I should be worried that mine wasn’t listed.
I never felt sick or dizzy but I would be breathing hard.
I don’t take aerobic classes anymore but I use an elliptical trainer (machine) that shows a digital display with readouts for speed, mileage, time, calories, and handle hand sensors for my heart rate.
Usually, with these types of machines, on the left side of the display is a graphic with a caption that says Target Zones or something like that. This elliptical trainer has 65% and 85% columns corresponding with age.
I never got that. Do they expect you to do math while you’re sweating bullets? I can’t do math, especially percentages, when I’m standing still or even sitting down! So, are you supposed to keep a calculator in the little book or drink holders that they provide? No. I finally got around to figuring out the answer. I will share that answer with you right here.
