"Warm-up is one of the most important elements of any exercise program.
It is particularly important to help prevent injury which should be completed prior
to stretching and more strenuous exercise."
The objective of the warm-up is to raise total body temperature and muscle temperature to prepare the entire body for vigorous activity.
The warm-up period prepares the cardiovascular system, respiratory system, nervous system and the musculoskeletal system by gradually increasing the demand on those systems so that they are able to accommodate the demands of more strenuous activity.
