Time/duration: acsm recommends 20 to 60 minutes of continuous aerobic activity. 60 minutes point of diminishing returns. Very little improvement in cardio work and increase risk for muscular skeleton injury. Deconditioned individuals may need to start with 10 to 15 minutes and progress gradually. Any activity that is continuous, rhythmic and uses large muscle groups: large muscle groups include legs. Selection of the exercise mode is made on the basis of the clients: functional capacity and skill level, time availability, equipment availability, personal/occupational goals, interests. They will not enjoy the workout and will probably drop it very soon after starting.

Intensity and skill are highly variable: e. g. , racquet sports, basketball, soccer, provides variety and group interaction, may not be appropriate for high risk or low-fit individuals.
