Alkuperäinen teksti - Englanti - Exercise, high intensity

Focus, commitment, maximum level of performance, and "pushing to the max" are all commonly recognized markers of intensity in exercise. Intensity may be defined as a maximum level of physical effort directed to a specific activity or movement in sport; as a matter of safety, the development of an athlete's physical skill will be the foundation of intense training, as intense efforts built upon poor technique often leads to injury and frustration.
