For best results and safety, the intensity of the interval workouts should be set using a percent of one's age-related maximum heart rate. An easy method of determining maximum exercise heart rate for interval work is to subtract your age from 220 and then use 90-95 percent of that figure. Remember too, interval training is very stressful on the body and joints and should not be done more than two times a week. Yes, young athletes are more resilient than master age-group athletes. They recover quicker and more fully between workouts which allows them to do interval training with greater frequency.
