Gender also is suggested to play a role, albeit inconsistently more about this later. In general, fitter people tend to have lower resting heart rates. Some great athletes of the past have recorded remarkably low resting heart rates.
For example, Miguel Indurain, five-time winner of the Tour de France, reported a resting heart rate of only 28 bpm. The reason for this is that, with appropriate training, the heart muscle increases in both size and strength. The stronger heart moves more blood with each beat this is called stroke volume and therefore can do the same amount of work with fewer beats.
As you get fitter, your resting heart rate should get lower. The second main factor affecting resting heart rate is state of recovery. After exercise, particularly after a long run or bike ride, several things happen in the body.

Fuel sources are depleted, temperature increases, and muscles are damaged. All of these factors must be addressed and corrected. The body has to work harder, and this increased work results in a higher heart rate. Monitoring your resting heart rate and your exercise heart rate will allow you to make appropriate adjustments such as eating more or taking a day off when your rate is elevated.
These same factors of recovery and injury also affect heart rate during exercise. The factors that elevate resting heart rate also elevate exercise heart rate. This is usually accompanied by a rapidly increasing heart rate throughout the exercise session. An extremely important factor affecting exercise heart rate is temperature.
Warmer temperatures cause the heart to beat faster and place considerable strain on the body. Simply put, when it is hot, the body must move more blood to the skin to cool it while also maintaining blood flow to the muscles.
The only way to do both of these things is to increase overall blood flow, which means that the heart must beat faster. Depending on how fit you are and how hot it is, this might mean a heart rate that is 20 to 40 bpm higher than normal.
Fluid intake is very important under these conditions. Sweating changes blood volume, which eventually can cause cardiac problems. The simplest and most effective intervention to address high temperature and heart rate is regular fluid intake.
