> How do you determine what 70% of your maximum heart rate is?
Hi Cyleilo-
I hadn't gotten as far as figuring that out yet. I know a lot of the exercise equipment (treadmill, etc.) at the gym I go to have sensors built into them on the handles that will measure your heart rate. As far as figuring out how to calculate your maximum heart rate (HRMax), I did find a link to a website that contains a discussion by various people on how to determine your maximum heart rate, and from there, you'd take 70%. The link is:

One simple way they say you can calculate it is: HRMax = 220 - your age. However, most of the folks seemed to think that was an innacurate method.
Others say you actually have to measure what your heart rate is when you're really exerting yourself hard exercising to determine HRMax, and they gave various suggestions for how to do that.
Then someone else gave something called the Karvonen Method for calculating a target heart rate (like 70% HRMax) as follows:
220 - age - resting heart rate = x
(x * target %) + rhr = target heart rate
Example:
220 - 30 (age) - 50 (rhr) = 140
140 * 70% + 50 = 148 (thr)I hope this helps!
