ACSM’s Guidelines For Exercise Testing And Prescription : Chapter 1

Physical fitness no longer has to be thought of in terms of running 5 miles/day x 7 days/week or having a specific VO2max in order to say that you are physically fit.

Physical fitness is now being defined more in terms of exercise performed several days per week for 30 + minutes using large muscle groups doing rhythmic exercise.

If a person is overweight but can still enjoy recreational activities & modest exercise training, & they have no risk factors or symptomatologies of cardiovascular disease, they can still say that they are physically active and fit.

“The exercise leader should recognize that excessive frequency (> 5d/wk) and duration (> 45 min./session) of training offer the participant little additional gain in aerobic capacity, yet the incidence of orthopedic injury increases disproportionately.”

For some physical conditions like type 1 diabetes mellitus and for obesity, exercise for 60 + minutes per session and 5-7 days/week may be warranted.
