  • Maximum heart rate varies for everyone. To get a general idea of how your heart may perform, take 220 and subtract your age. This gives a rough estimate of your maximum heart rate. While exercising, you will most likely never reach this number. During exercise we can reach anywhere from <60-95% of our maximum heart rate depending on the intensity.

    Alcohol is a diuretic. As such, it causes people to lose intravascular volume. In response to this drop in volume, the heart increases its flow by first increasing the force of contraction with each heartbeat, then later by increasing the heart rate to make sure blood pressure is maintained.
