Heart rate is just one way to measure the intensity of your workout. Anyone who takes a medication that lowers heart rate should use another method to measure intensity- such as the Talk Test or Rate of Perceived Exertion. As long as you are working hard and challenging yourself, that's what matters most- not the specific number your heart rate reaches.
Hope that helps,

I take the medication propanolol as a headache prophylactic and it has the side effect of lowering my heart rate. So, I am about 50-60 resting and get up to maybe 140 max while working out, even if I am doing high intensity cardio. Does this mean I am burning fewer calories than if I was off the med and my HR was up to 170-180 like it used to be? I know I need to ask my doctor, but I was hoping someone here may have some unofficial insight first. Thanks for any help!
