How many times per minute should your heart beat while you're exercising?
It used to be really easy to calculate what your maximum and target heart rate for working out should be - you just took your age, subtracted it from 220 and that gave you your maximum heart rate. You would then try to keep your heart rate between 50% to 80% of that number to get the best cardiac workout that medical professionals could recommend.
But then, while that math works for men, it turns out that math doesn't work for women!
Fortunately, a new math formula for finding the maximum and target heart rates for women has been developed: all a woman needs to do is to subtract 88% of their age from 206 to find their maximum heart rate number, then keep their pulse rate between 50% and 80% of that result while exercising!
Since that really isn't the kind of math that people can do in their heads, our latest tool is designed to take your head out of the picture, so you can focus on that workout of yours, regardless of whether you're a man or a woman!
Just enter the indicated data into the tool, and we'll tell you just how fast you need to get your blood pumping while you're working out on that new-fangled treadmill....
So there you go - now give us 20!
