Body composition

Components that make up the human body and the proportions of these components, specifically the relative amounts of fat and fat-free mass in the body.

Exercise

Type of planned, purposeful physical activity with the goal of improving or maintaining physical fitness.

Functional capacity

Resistance training

Form of exercise that uses free weights, bands, machines, or body weight to put resistance on the muscle through full ROM (range of motion).

Warm-up

Easy activity at the start of a workout to prepare the body for activity by increasing heart rate, blood flow, deep muscle temperature, respiration rate, viscosity of joint fluid, and perspiration.
