Frequency Of Exercise 1.0 Frequency of Exercise is the first component of successful cardiovascular exercise work out plans. You should exercise at least three days a week. Those who are very out of shape and/or who are overweight and doing weight-bearing cardiovascular exercise such as an aerobics class or jogging, might want to have at least 36 to 48 hours of rest between workouts to prevent an injury and to promote adequate bone and joint stress recovery.
