The Next Evolution in heart-rate science.


Blood lactate testing is a thing of the past.

For the price of about one trip to get your lactate threshold test, you can essentially just buy the lab, now.

Use it anytime you want from then on. No additional charges.

Plus, you get subscription free Heart Rate Variability (HRV) Stress monitoring.

This gives you constant clinical insight into the stress levels of your internal systems.

“It makes sense, now… It’s like somebody turned the light on, and I can now SEE what I need to achieve during the time I am exercising on the machine I use… to train my heart correctly. Very COOL!“

Eric F. – 2019

“I use it to track how my stress levels feel while I am playing my intense computer games… I’m much more deadly and effective when I am low stress… this shirt is making me a better gamer.”

Justin D. – 2019

This helps me keep training runs in the zone I am trying to be in. I always used to run a little faster than Zone 2… now I have that defined for me, and I know what I am achieving in my training.
