Redefining human performance through science and data.
Bridging the gap between sports science and the everyday athlete — turning decades of physiology into insight anyone can act on.
Born from a question about human potential.
MyBya was born from a vision to revolutionize athletic performance through science and data. Founded in 1999 by Shannon Grady — a world-renowned sports physiologist, elite runner, triathlete, and author of The Lactate Revolution — it began with a groundbreaking approach to understanding human performance.
Shannon developed the platform through the analysis of over 100,000 athlete biomarker and biometric samples, combined with extensive training and performance data — a repository meticulously collected across decades. What started as a mission to bridge sports science and practical application has grown into a platform that empowers athletes and coaches worldwide.
The best training plan is written for one body.
Turn the science into a personal record.
One test, personalized zones, and a plan that respects the physiology it was built from.
