Interval Training

Get out of your exercise slump with interval training – add short bouts of intensity to your cardio workouts to increase endurance and prevent a plateau. Set your Classic Gymboss and miniMAX intervals for high-intensity and lower-intensity to push beyond your comfort zone. Program the miniMAX for interval ladders to increase the length of work and decrease the length of recovery during a workout. The miniMAX saves up to 20 programs making it great for interval training programs that require fast recall of programs you wish to do in sequence.
