<h3>What is a strenuous exercise?</h3>
A strenuous exercise is one that takes a lot of energy from the person that is engaging in it. Being engaged in a strenuous exercise would mean that the person would sweat so much and loose a lot of fluid in the process.
In the course of strenuous exercise, it is possible for a person to become dehydrated especially on a hot day when the temperature is as high as 81°f and the relative humidity is 80 percent.
