"My VO2 max improved approximately 8% in just 4 weeks, damn good".
"Overall, I've noted lower resting HR, increased lung capacity, with generally longer, deeper breaths while normal breathing, likely activating the parasympathetic nervous symptom resulting in a lot calmer mood, less cortisol, and less tiredness".

"I highly recommend STEALTH for on ice and off-ice HIIT - High Intensity Interval Training such as sprinting coupled with lower intensity jogging.
Sprinting or biking intervals 20 to 30 sec at maximum speed, followed by 60-90 seconds low intensity jogging or cycling for 8 to 10 reps is a good starting point to improve and push lactate threshold upwards. Lactate threshold will improve by using this device.
The higher your level of conditioning, the harder it is to get your heart rate up. STEALTH RMT device can shorten that time and prevent overtraining. Practice should always be harder than gameday, thus using Stealth Fitness Accelerator in practice will make your players much more effective when breathing without airflow restrictions during game situations."

"As a former NFL player I personally have benefited greatly from this device by increasing my strength and endurance, VO2 Max, Lactate Threshold, learning to deeply breathe diaphragmatically for optimal health, fitness and overall well being.
Breathing is one of the most important function our bodies perform 24/7/365, yet few of use are efficient at breathing.
Deep breathing helps all of us deal with and manage stress levels as well as improve fitness.
Resistance breathing, deeply during exercise is a force multiplier for fitness improvements and stress management.
Over 40 weeks now using STEALTH my strength has increased over 80% on average and endurance has seen equal increases."
Paul H | Former Pro Athlete | Biotech Executive
"Using STEALTH has truly been a game-changing experience for me.
After 8 weeks using STEALTH my strength increased on average 40% over baseline across all exercises.
The only thing I changed in my workouts was added STEALTH, nothing else was altered.
With focused breathing work, alongside my strength and endurance training, there was a big impact on my quality of life.
I have been sleeping through the night and my wife noticed that I’m not snoring anymore.
My blood pressure has improved and I’m much more relaxed at work, even though I work in high pressure start up world."

"I would 100% absolutely recommend this device to anyone looking to improve overall fitness related performance as well as an overall improved sense of well being.
I shaved 30% off my time in the 2.5 mile cycling test and increased my strength on average 27% across exercises.
While I cannot be certain that Stealth will add years to your life, I can assure you that it has added life to my years."
Non-fitness related benefits I have experienced from using Stealth device include an overall improved sense of well being, heightened awareness & I've even noticed some memory improvement.
I have experienced much better sleep quality since I started using STEALTH.

"I would highly recommend this device to anyone looking to take their fitness to the next level."
"As a certified strength and conditioning coach, the premise of how the device works made sense to me and I had to try it out. The results surprised even me!
I increased my max WATTS on Peloton from of 457 to 510.
My strength increased on Incline bench press up 62% and pull-ups increased by 39%.
I see this device truly setting a new performance standards across all sports."
