How does heart rate change with exercise experiment?

Why is my resting heart rate increasing with more exercise?

The capacity of your left ventricle will increase and your ventricular muscles will become stronger which leads to an increased stroke volume. That is, your heart will pump more blood per beat than before.

What should heart rate be sleeping?

What does resting heart rate tell you?
A “normal” RHR falls between 60 and 100 beats per minute. An RHR under 60 can indicate that you’re more physically fit and may be associated with better heart function. An RHR that is above 100 beats per minute can reflect exposure to stress, excessive caffeine consumption or an illness.
