warming up

A warm up is usually performed before participating in (technical) sports or exercising. A warm up generally consists of a gradual increase in intensity in physical activity. For example, before running or playing an intense sport one might slowly jog to warm muscles and increase heart rate. It is important that warm ups should be specific to the exercise that will follow, which means that exercises should prepare the muscles to be used and to activate the energy systems that are required for that particular activity. The risks and benefits of combining stretching with warming up are mixed and in some cases disputed. Warming up prepares your body mentally & physically.
