It is important to chose the type of exercise we want to get involve in carefully; the type of exercise, the exertion requirement and the duration of the exercise should be considered carefully based on one's health status because our body react differently to exertion. When one has been away from exercise for a long time, it is important that such a person consider the length of time he is been away because, his body system may react adversely if he start doing very strenuous exercise suddenly. If he has been away for a long time, then he has to start the exercise gradually, beginning with minimum exertion and then build it up gradually over a period of time.
