Technology at a Glance
How the AI Works
Fit PA combines a conversational AI coach with established sports-science models — not a black box, but a coach that reasons over your real training data.
Conversational AI Coach
Your AI coach understands your training history, goals, and recovery, and talks with you in plain language to plan, adjust, and explain your training.
Established Sports-Science Models
Your analytics use proven methods — training load (TSS, CTL, ATL, TSB), heart-rate zones, and the VDOT race-time model — so the numbers behind your plan are transparent and trusted.
Adaptive Plan Engine
Your plan is built around your goal and current fitness, then adjusts as your training load and recovery change week to week.

Your health and fitness data deserves strong protection. Fit PA follows solid security practices and puts you in control of your data.

Technology FAQ
How is prediction accuracy validated?
Fit PA's race-time estimates come from the established VDOT model (Daniels-Gilbert), a widely used sports-science method that maps a recent performance to equivalent times and training paces across distances from 5K to the marathon and beyond. They're guidance for goal-setting and pacing, not guarantees.
What powers Fit PA's coach and analytics?
Fit PA pairs an AI coach that understands your training data with established sports-science analytics — training load (TSS/CTL/ATL/TSB), heart-rate zones, and the VDOT race-time model — so the guidance is personal and the numbers are transparent.
How is my data protected?
Your data is encrypted in transit and at rest and protected by strict access controls. We never sell your data, and you can export or delete it at any time. You can read more in our Privacy Policy.
Does the AI improve over time for my specific needs?
Yes — the more you train, the more context your coach has. It remembers your history, preferences, and how you respond to training, so its guidance and plans become increasingly tailored to you over time.
What happens to my data if I stop using Fit PA?
You have complete control over your data. You can export all your training data at any time in standard formats. If you delete your account, all personal data is removed within 30 days, with backup data purged within 90 days. Anonymized, aggregated data may be retained to improve the service but cannot be traced back to you.
