Exercise: A form of physical activity of sufficient length and difficulty to produce sustained perspiration, elevated heart rate and respiration rate. Walking, running, lifting weights, swimming are some examples of exercise provided that the activity produces perspiration.
Fascia: A specialized connective tissue that surrounds muscle, bone, joints and internal organs providing support and giving structure to the body.
Fatigue Index: An ordinal scale from 0-10 where 0 = no fatigue and 10 = extreme fatigue. Used to determine the difficulty of a particular drill or exercise.
Fatigue: The inability to continue functioning at a prescribed work rate in the presence of an increased perception of effort.
Fitness: the state of being suitably adapted to the demands of an environment or situation and across a set of specific physical standards.
Fracture: The separation of a substance into pieces following the application of physical stress.
Frustration: The feeling that accompanies an experience of being thwarted in attaining your goals; a form of anger.
