Resting heart rate:
A resting heart rate predicts longevity and cardiovascular disease, and current evidence suggests that it is also an important marker of outcome in cardiovascular disease, including heart failure. A normal heart rate is between 60-100 beats per minute at rest (sitting, relaxing, etc.). It is well-known that the average resting heart rate for well-trained athletes is 40-60 beats per minute!
Exercising heart rate:
To determine what a normal exercising heart rate is, you first need to determine your age-predicted maximal heart rate. Here is the generalized equation for predicting maximal heart rate (HRmax) in healthy adults:
HRmax = 208 – (0.7 x age)
Generally, during exercise, you want your heart rate to be at 50-90% of your maximal heart rate. This range should be considered your general target heart rate during exercise.
For Leo: max is 186.
50%=93, 90%=168
For Lee: max is 164
50%=82, 90%=148
