STEALTH Performance Optimizer 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. 

Because the training load is significantly increased, your heart rate and caloric burn are significantly increased as well as 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.

STEALTH Optimizer has Dual Resistance Airflow Technology designed for maximum results. The more you wear the Stealth Optimizer while exercising, the greater your results will be.  It is an advanced (CRMFT) Cardiovascular Respiratory Fitness Trainer 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.

The STEALTH Performance Optimizer Device offers multiple resistance levels for all athletes. Regardless of your level of fitness, it is recommended you start by using only the mouthpiece to acclimate to resistance and gain a level of comfort with the device.  

Valve body and mouthpiece are two parts and can easily be separated.

STEALTH Performance Optimizer Device is a cardiovascular respiratory training system that improves athletes conditioning and performance via wearing the Optimizer while you workout, practice, exercise, run, cycle or train.  

Using STEALTH Performance Optimizer Device while you train, or practice increases lung muscle strength, lung efficiency, accelerates your entire cardiorespiratory workload, rapidly and significantly improving both VO2 Max and Lactate Threshold.

STEALTH Performance Optimizer Device is a first-in-class, scientifically designed cardiorespiratory fitness accelerator training device for athletes to use while exercising, designed to maximize athletic performance on game day when not using the device.

The device is designed fit into mouth via mouthpiece and used during exercise breathing solely through your mouth while exercising.  You should avoid breathing through your nose while using the device in order to maximize the cardiorespiratory load and maximize exercise benefits over time.  If you find yourself needing to breathe through your nose you should reduce resistance level or remove device.  

When not using the device breathing through your nose is the most efficient way to breath, both when exercising and not exercising.

Because you use the device while exercising, while increasing airflow resistance into and out of your lungs, the training load on your cardiorespiratory system is much greater than exercising without using the device.  Because the training load is significantly increased, results from your training efforts are also significantly increased thus optimizing training results when not using the device for enhanced game-day cardiorespiratory performance.

The more you use the device the greater your gains.  However, as with any training device, you should progress gradually over weeks in order to acclimate and not overtrain.  If the training gets too intense, take a break.

When you use the STEALTH Performance Optimizer Device you should focus on deep diaphragmatic, or belly breathing.  Deeply and fully inhaling, exhaling airflow into and out of lungs.  If you find you are shallow breathing you should reduce airflow restriction level or stop exercising and remove STEALTH Performance Optimizer Device.

Stepwise device usage recommendations:

Regardless of your level of fitness, you should follow a five step process to begin use and progress with device:

1. Start by using only the mouthpiece, with valve body removed, to acclimate to resistance breathing through the mouthpiece in order to gain comfort with resistance breathing through your mouth and mouthpiece only.

Do not breathe through the nose when using device, only breathe through mouthpiece and the device when in use. 

Use while walking, breathing very deeply fully inhaling and exhaling.   Gradually advance to using mouthpiece only (valve body removed) with mild to moderate exercises, jogging, etc., while breathing deeply, fully inhaling and exhaling only through mouthpiece.  

Once the user has a level of comfort and confidence you can proceed to step 2 below.

2. Insert valve body into mouthpiece ensuring a tight fit and set to level #1.  Begin using device while walking, jogging short distances, and light exercise.  Gradually increase exercise intensity over time practicing diaphragmatic deep breathing, fully inhaling and exhaling.

3. Once you are able to use device at level #1, for your exercise routine, practice, etc., employing diaphragmatic breathing, fully inhaling and exhaling with a level of comfort and confidence you can proceed to level #2.

4. Repeat step 3 before progressing from level #2 to level #3

5. Repeat step 3 before progressing from level #3 to level #4

6. Repeat step 3 before progressing from level #4 to level #5

Precaution: As with any exercise program you should stop exercising and remove device if you feel light headed or begin to hyperventilate.  Always focus on deep diaphragmatic breathing when using device and deep diaphragmatic breathing through nose when not using device.

Progressing from mouthpiece usage to level # 1 can take a week or two, depending on frequency and duration of device use.  Once you can breathe through the device and mouth only, without nose breathing, you can move to the next level.  if you find you are breathing through your nose, reduce level until only breathing through device, then advance to next level.  

Always consider Intensity of exercise, duration of exercise and airflow resistance levels when acclimating to device.  

The more you use device the greater the benefit, assuming you are not overtraining.

16 Weeks REAL WORLD USER EXAMPLE | No Device Use During Test

 

Testing Result will vary pending the following variables:

- Level of current athletic performance and conditioning

- Level of airflow restriction employed (always start with valve body removed from mouthguard for acclimation)

- Duration of airflow restriction

- Frequency of device use per day, per week 

- Number of weeks lung trainer used (8 weeks min for best results) 

^{Traditional breathing training devices (RMT) were designed for sick people with asthma, COPD, cardiac surgery rehab, etc.  These basic breathing trainer used as directed, will afford some benefits for sickly patients, the impact, benefit is minimal at best, in healthy athletes.}

^{Because only STEALTH was scientifically designed with dual resistance airflow technology for healthy athletes to be worn while exercising, affording user a significantly greater cardiorespiratory load increase resulting in significantly increased heart rate, breathing difficulty, hypoxia, caloric burn significantly improving both lactate threshold and VO2 Max over time.}  

^{The increased cardiorespiratory load creates a much greater performance improvement over a period of eight weeks.}  

^{Until now, lung trainer breathing devices had to be used independently of specific sport conditioning or exercise, thereby adding to overall training time, without the benefit of improving upon specific sport ventilatory demands in specific sport applications, with only minimal impact on performance improvement.}  

^{Again, these devices were designed for sick patients, not healthy athletes.} 

^{Most traditional breathing trainers only offer airflow resistance while breathing in, inspiratory airflow resistance.  Thus only working half of the lung muscles, half the respiratory equation and they are not used during exercise thus the load on the cardiorespiratory system is minimal, lungs only, thus any improvement minimized.} 

As a healthy athlete, two-way airflow resistance during exercise challenges the cardiorespiratory system greatly.  Much more than exercise alone, thus providing a much more potent and significant cardiorespiratory performance improvement in both VO2 Max, and Lactate Threshold. 

Once you acclimate to the device and you gain a level of comfort, confidence in using it, you can use the STEALTH device as often as you like, assuming you are not overtraining.  

That is why a Polar H10, or other top quality HR monitor is important to use while exercising as you can monitor your training zones in order to prevent overtraining.

Prototype users have used the device up to 10 hours in a week, depending endurance or power athlete, exercises, HR, zone training, percentage HR max, etc.  That does not mean you could not use it more often depending your level of fitness, endurance, power athletes.

The more you use device the greater the acclimation becomes and the more you want to use the device over time.

Always use caution as to not overtrain, thus HR monitors use recommended while using STEALTH.

Heart rate monitors are recommended during use in order to prevent over-training and maximally improve lactate threshold via lactate threshold training programs.  

If you are not educated on lactate threshold training and VO2 Max training, you should read up before using this device for such training. 

Polar H10 is the recommended HR Monitor for use with this device.  

Go to polar.com and search for Lactate or VO2 Max training.

Fitness watches with HR monitors are helpful, however for most accurate HR data an H10 Polar HR monitor is recommended.

Choose three to four exercises that are active in your daily, weekly exercise routine and will continue to be active through 16 weeks.  

If you typically run several days per week a 2 mile run for time could be one good baseline exercise.  

If you do pull-ups, chin-ups, pushups, during your workouts, these exercises would be good to include in your baseline test.  

You will use the same testing at baseline, weeks 8 and 16 for results comparison.  

You should only include exercise in your baseline that you will include in ongoing workouts.

Bodyweight exercises are recommended to help prevent injuries.  You should not lift heavy weights, choose light weights you can easily rep out until failure.

Real world device user example below.

Results vary depending baseline level of fitness, frequency and duration of use as well as intensity level.

The more you can safely use device the greater your results.

During initial device usage more saliva will generally be produced since you have a mouthpiece in.  

Over time, with increasing usage of device your mouth will acclimate to device with less saliva production.  

Since there will be saliva present during use, it is important to keep your device clean after daily use.  See cleaning instructions.

Use only dish soap and hot water to clean as harsher cleaners can degrade device materials.  

A simple five step cleaning process includes the following:  

1. Separate Valve Body from mouthpiece.
2. Wash Mouthpiece using mild dish soap and hot water.
3. Wash Valve Body using mild dish soap and hot water.
4. After washing valve body, thoroughly rinse with hot water and shake out excess water while towel drying exterior.  
5. Place on paper towel with valve body grill facing down.
6. Simply air dry in a non-humid location until next use.
7. Do not use the dishwasher to clean the STEALTH Performance Optimizer Device.

STEALTH device has two main parts:

The mouthpiece and the valve body.

The valve body is easily removed from the mouthpiece by pulling valve body out and away from the mouthpiece.

This separation should be performed when cleaning device.

See daily cleaning instructions.

As with any device use it will take time to acclimate to using device in mouth and breathing through dual resistance airflow.  

It can take several weeks to fully acclimate.

If mouthpiece does not fit comfortably and properly in the mouth, you can trim the mouthpiece material to customize a more comfortable, custom fit.

As you continue to wear it over periods of time during exercise, you will acclimate to the device use.
