"As a lifelong Strength & Conditioning Coach, I have used STEALTH and will continue to do so in order to maximize my fitness and overall well being. I would highly recommend this device to anyone looking to take their fitness to the next level."

"As a certified strength and conditioning coach, I was skeptical about STEALTH claims, however the premise of the how the device could improve performance made sense to 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 40%.

I see this device truly setting new performance standards across all sports."

"As a former NHL Strength & Conditioning Coach 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 to 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, to learning to breathe deeply for optimal health, fitness and overall well being.

Breathing is one of, if not the most important functions our bodies perform 24/7/365, yet few of us maximize breathing. Deep breathing helps all of us deal with and manage stress levels and increase fitness.

Resistance breathing, deeply during exercise is a force multiplier for fitness improvements and stress management.

After 30 weeks using STEALTH my strength has increased over 80% on average and endurance has seen increases up to 60%. and my stress management is better than ever, by far."

"Using STEALTH has truly been a game-changing experience for me. After 8 weeks using STEALTH my overall strength increased on average 40%.

The only thing I changed in my workouts was adding STEALTH.

With focused deep breathing work during my strength and endurance training, there is 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."

Paul Howe | Former Professional Athlete | Biotech Executive

"I would 100% absolutely recommend this device to anyone looking to take performance to the next level.

I shaved 30% off my cycling time in the 2.5 miles and increased my strength on average 27% across all exercises.

While I cannot be certain that Stealth will add years to my 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, improved memory and overall sense well being.
