How do you define cardiorespiratory endurance muscular strength and physical activity?

Cardiorespiratory endurance is the ability of the heart, lungs, and blood vessels to supply oxygen to the body's muscles during prolonged exercise. It is often measured by the VO2 max, which is the maximum amount of oxygen that the body can use per minute.

Muscular strength is the ability of a muscle to exert force. It is often measured by the one repetition maximum (1RM), which is the maximum amount of weight that a person can lift once.

Physical activity is any bodily movement that results in an expenditure of energy. It can be classified as either aerobic or anaerobic. Aerobic activity is activity that uses oxygen as the primary source of energy, such as walking, running, and swimming. Anaerobic activity is activity that does not use oxygen as the primary source of energy, such as sprinting, weight lifting, and jumping.
