STEALTH was scientifically designed for use while you exercise to maximize sports performance by placing a greater cardiorespiratory load than exercise alone, thus significantly improving CRF.

* Maximally & Rapidly Increases Lactate Threshold 

* Maximal & Rapidly Increase VO2 MAX

* Maximally Increase Caloric Burn

* Accelerates HR getting you into Training Zone

* Increases Lung Muscle Strength

* Increases Lung Function Efficiency

* Promotes Deep Diaphragmatic Breathing

* Improves Muscle Tissue Oxygenation

* Maximizes Game-Day Performance

* Improve HRR - Heart Rate Recovery

* Reduce Resting Heart Rate

* Breakthrough your training plateau

See Real World RESULTS Examples Below.

Baseline Polar VO2 Max score was 40, rated very good. 

After 12 weeks of using ALT device, VO2 Max score improved to 50, ELITE level.

Results variable depending VO2 Max of athlete at baseline.  Higher VO2 Max athletes have less room to improve while lower VO2 Max athletes have much more room to improve.

Results also dependent upon frequency of using device, resistance level you train with, duration of training, etc.

Use of HR monitor is recommended to maximize training and prevent overtraining.

"If I could have accessed a device like this when I played in the NFL, it would have been a game-changer." NFL Alumni prototype user.

Maximum repetitions until failure.

Device not used during baseline, 8, 16 week tests.

Significant pronounced improvements in number of repetitions across all exercises. 

Over 40% improvement in repetitions across all exercises after 8 weeks.

65% to 117% increases at 16 weeks of device usage.
Results will vary pending usage of device, duration of usage of device.

Baseline cycling at 94% max HR cycling for 5 minutes.

After 8 weeks using STEALTH device, user cycled at 94% of Max Heart Rate for 31 minutes breathing deeply through nose only.

The first and only scientifically designed cardiorespiratory performance improvement device designed to be used while you exercise, or practice for sport specific conditioning sessions.  

By using the device while you exercise the "training load" on you cardiorespiratory system is greatly increased. Thus the benefits and performance outcomes, improvement over baseline are also greatly enhanced.

Because STEALTH Cardiorespiratory Fitness Accelerator is designed for use while you exercise, your increases in both Lactate Threshold and VO2 Max are significantly enhanced.

Ergo-dynamically designed to be worn comfortably while you exercise or practice your sport allowing for a sport specific workouts and results.

Adjustable Dual Airflow Resistance Technology allows users to dial up airflow resistance to rapidly increase Cardiorespiratory Fitness improving both VO2 Max and Lactate Threshold to maximize your game-day performance.
