How does pulse rate differ on people of different fitness's?

Pulse rate typically varies between individuals based on their fitness levels. Generally, more fit individuals tend to have lower resting heart rates due to more efficient cardiovascular systems, as their hearts can pump more blood with each beat. During exercise, fit individuals also usually experience a quicker return to their resting heart rate compared to those who are less fit. This difference reflects the body’s ability to manage physical stress and recover efficiently.
