More PRs. Powered by PRS.
MyBya is your personal physiologist. One simple at-home test turns your physiology into the zones, paces, and daily readiness that turn training into records — so you train smarter, not harder.
Most training plans guess — the same paces for everyone. MyBya measures what your body is actually doing, distills it into a single readiness score, and builds every workout around it. The higher your PRS, the more ready you are — and the more personal records follow.
Free to start. Keep all data forever. Syncs with Garmin, Polar, Wahoo, and Strava.
HOW MYBYA WORKS
From one test to a season of records.
STEP 01
Test at home
A sport-specific protocol for running, cycling, rowing or swimming. No lab, no appointment.
STEP 02
Get individualized zones
Personalized zones, pace and power targets, and Bioenergetic Power Scores tuned to exact physiology.
STEP 03
Train to readiness
Workouts respect PRS. Push on prime days, recover on depleted ones. Syncs with Garmin, Polar and Wahoo.
STEP 04
Bank the PRs
Showing up ready more often is what makes records follow. Track every personal best in the app.
Where MyBya sits alongside familiar tools.
Not here to replace a GPS watch or a coach's workflow — here to fill the gap neither does: measuring the physiology that makes every other number meaningful.

— FOR COACHES
Coach the unique athlete — not the average.
Objective, individualized prescription for every athlete on the roster. The physiology, handled. The coaching, still the coach's. And flat pricing that doesn't punish growth.
For 30+ years, the MyBya methodology has given world-class coaches an edge: prescription grounded in each athlete's measured physiology. Now that engine runs an entire practice — testing, zones, periodization, day-to-day adjustment — leaving less time in spreadsheets and more time coaching.
WHAT'S INCLUDED
Objective data behind every decision.
Individualized training
Per-athlete zones, pace and power targets, and system-based prescription from real test data.
Roster-wide monitoring
Readiness, resilience, and adherence at a glance.
Training-intensity management
Holds athletes to the prescribed system and effort.
Objective assessment
Retest to confirm adaptation instead of guessing.
Race & competition strategy
Planning and pacing built off real-time physiology.
Injury prevention
Catch overload early with load-aware monitoring.
Nutritional guidance
A shared plan-versus-actual picture keeps everyone honest.
Athlete feedback
Two-way notes tie prescription to how each session actually felt.
— FOR ATHLETES & FITNESS ENTHUSIASTS
A lab-grade physiologist, in every athlete's pocket.
A watch reports how the night went. MyBya shows how to train. Measure real physiology, train to readiness, and watch the personal records stack up.
Whether the goal is an Olympic Trials qualifier or simply feeling fitter this year, MyBya delivers what elite athletes have always had. The Garmin, Polar, or Wahoo already in use stays in use — MyBya syncs with it and adds the layer it can't provide.
✓ Free to start. No credit card. Keep all data forever, even without upgrading.
WHY ATHLETES CHOOSE MYBYA
The only app that trains off real-time physiology.
The best training plan is the one written for the body in front of it — individualized intensities, paces, and daily workouts derived from measured data, not a chart or last night's sleep.
01
Training-load monitoring
Know when fitness is building and when the hole is getting deeper.
02
Personalized zones
From a real test — not a formula based on age.
03
Individualized plans
Sport-specific, and matched to current readiness.
04
Performance prediction
See fitness trending toward the goal.
05
Fatigue management
Push on prime days, recover on depleted ones.
06
Fueling strategies
Align nutrition with real metabolic demands.
THE LACTATE ADVANTAGE
Lactate is the most honest signal the body gives.
Not a waste product to fear — it's the body's energy currency, and a real-time readout of how the energy systems work under load. MyBya translates that signal into workouts that target exactly what will move performance, while keeping injury risk low.
For the science-minded
Anchoring zones to measured lactate dynamics — rather than a percentage of an estimated maximum heart rate, or an overnight HRV proxy — is what separates true individualized prescription from population averages. MyBya models each athlete's lactate–workload curve to place threshold boundaries precisely, then re-checks them as adaptation occurs.
WHY PROGRAMS CHOOSE MYBYA
Individualized at scale, monitored in one place.
Depth wins seasons. MyBya delivers elite-level prescription from the top scorer to the middle of the roster — while staff monitor readiness, adherence, and adaptation across every athlete from one dashboard.
01
Performance optimization
Every athlete trained to their own physiology, not to a team average.
02
Roster-wide monitoring
Readiness, resilience, and adherence for the whole squad.
03
Strategic planning
Periodize the season with objective checkpoints.
04
Injury-risk reduction
Load-aware flags across the program, not just for the stars.
05
Objective development
Retest to prove progress and defend decisions.
06
Clear per-athlete budgeting
Onboarding plus a simple per-athlete rate that tracks the roster.
Start free. Everything needed is included — no per-athlete surprises, and no separate testing tool to buy.
Simple pricing, whoever you train.
