The definition of physical activity is "any body movement produced by skeletal muscles that results in energy expenditure above resting level." This definition is frequently cited by health organizations, medical professionals, and fitness specialists worldwide. [1, 2]

In layman's terms - physical activity is any movement that requires your body to work harder than it does while sitting, or resting. This includes activities like walking, cycling, gardening, & dancing.

"Is the Definition of Physical Activity Synonymous

Physical activity, exercise, and physical fitness are not synonymous - although they are sometimes used that way. According to health and wellness scientist C J Caspersen, each of these terms has a distinct definition. [3]

Physical activity definition - (see definition of physical activity above.)

Physical fitness definition - generally refers to a set of health-related attributes (endurance, strength, body composition, flexibility) or skill-related attributes (referring to athletic ability).

Exercise definition - planned, structured, and repetitive physical activity focused on improving or maintaining a particular level of physical fitness.
