Warming up is an important part of physical activity (PA). It is performed prior to the main PA, such as exercising, playing sports, or working. This allows the body to increase muscle temperature by getting the blood flowing and preparing the individual for the PA. Warm-ups decrease the risk of injuries from occurring. They should be body-specific to the demands of the activity. For example, an individual going for a 5k run during the fall season should ensure that the lower body muscles are warmed up by performing hamstring sweeps, lateral wall leg swings, a five-minute walk, and then a five-minute jog.
