PHYSIOLOGICAL READINESS SCORE

More PRs. Powered by PRS.

MyBya is a personal physiologist. One simple at-home test turns complex physiology into individualized zones, paces, and watts that turn training into records — so each athlete trains smarter, not harder.

Most training plans guess — the same paces for everyone. MyBya measures what each athlete's body is actually doing and distills it into a single physiological readiness score or PRS. MyBya's proprietary, advanced lactate testing analytics builds every workout to match each athlete's physiological readiness. MyBya meets athletes where they are. Improving PRS, the more ready the body is — and the more personal records follow.

25 YEARS OF LACTATE DATA ANALYSIS

The science came first. The app came after.

100,000+ Athletes
MyBya's lactate based training model is based on over 100,000+ athlete tests across all sports and levels including running, cycling, rowing, swimming, soccer, football, tennis, pickleball, Hydrox, MMA, and more.
Champions Coached
100s of Olympic, World, National, and NCAA champions have used the MyBya lactate-based training model.
Advanced Lab-Grade Testing & Analytics Made Easy
MyBya's proprietary, advanced lactate analytics platform is built to support any athlete, any coach, and any team. A simple finger-prick test any time, any place. Same science, more convenience.
Physiological Readiness Advantage
MyBya is the ONLY platform available that provides customized training plans, individualized zones, pace, and watts targets based on real-time biomarkers and physiological readiness.
WHY MYBYA IS DIFFERENT

Measured, not estimated.

Mainstream wearables readiness scores infer from three overnight proxies — heart-rate variability, resting heart rate, and sleep — while the body is at rest, validated against no laboratory standard. The PRS is built on measured metabolic response: real-time lactate dynamics captured under load. Not a feature difference. A category difference.

THE LACTATE ADVANTAGE

Lactate is the most honest signal the body gives.

Lactate is NOT a waste product to fear — lactate is the body's energy currency, and a real-time readout of how the body works under load. MyBya's proprietary, advanced lactate data analytics translates biomarker and biometric data into actionable plans. MyBya turns complex data into customized workouts that target exactly what will improve physiology and performance, while keeping injury risk low.

FOR THE SCIENCE-MINDED

Anchoring zones to real-time lactate dynamics — rather than a percentage of an estimated maximum heart rate, "lactate threshold" or an overnight HRV proxy — is what separates true individualized prescription from population averages. MyBya's proprietary, advanced lactate testing analytics models each athlete's lactate systems to precisely train each athlete. Every new test updates zones, targets, and training plans as adaptation occurs.

HOW MYBYA WORKS

From one test to a season of records.
