Duration Time of Day  Intensity

Very active exercise should not be taken after a full meal.  Active exercise before breakfast is not generally beneficial.

Hatfield, 258.

Exercise shall be continued until a feeling of glow or warmth of surface, or a slight perspiration.  It can be continued beyond this point without harm, but the value of exercise is reached before this point.  Fatigue is always a sign of needed rest or a change in mode of exercise.

Hatfield, 258-9.
