Age related: Your "maximum predicted heart rate" (mphr) is derived from your age. It is 220 minus your age. Note that this is a simple derived number, and actually has very little to do with actual physiologic limits of your own body. My usual advice regarding "maximal heart rate" is to use mphr as a general guide only. "listening to your body" is a better way of guiding exercise limits.
