Why is it important for people to exercise raise their pulse?

This is because if you are not careful, your heart rate can increase to an extent where it forces the pancreas to create hormones continuously....this leading to your penis to erect 3 times its average size and for your testicals to continuously produce sperm, and for you to have continuous orgasms with no way to prevent them from taking place (same principle occurs within women).

It is very important to keep your heart rate steady and the matter is taken very seriously as you can pass out from too much orgasms....this occurs because each time you orgasm your body feels weaker and loses energy, if your body has no energy left then it will collapse and have a breakdown.
