MAXIMUS Fitness Accelerator Device is a first-in-class device scientifically designed for athletes to use while exercising, HIT training, running, cycling, practicing, or sport-specific conditioning.  Because you use the device while exercising, the training load on your cardiorespiratory system is much greater than exercising without device use. Using MAXIMUS during exercise significantly increases the load on your cardiovascular system. Thus lung and heart work much harder than exercise alone, caloric burn is increased dramatically, and accelerated lactate production, muscle burn, and a decreased time-to-fatigue. Because of this overall increased load, added to your existing training efforts, significant performance improvements can be expected, over and above generally seen with exercise alone.MAXIMUS Fitness Accelerator has Dual Resistance Airflow Technology designed for maximum results. The more you breathe through the MAXIMUS device while exercising, the greater your results.  MAXIMUS is an advanced (CRFA) Cardiovascular Respiratory Fitness Accelerator device designed to be used while exercising for your sport, increasing the workload on the cardiorespiratory system, thus maximizing your results on game-day or event day when not using the device.Using MAXIMUS Fitness Accelerator while you train or practice increases lung muscle strength and lung efficiency, accelerates your entire cardiorespiratory workload, rapidly and significantly improving VO2 Max and Lactate Threshold.
