Four Essential Phases of Training Design

FitLogic enables true data-driven training throughout the four essential phases of training design (Assessment, Prescription, Evaluation, Prediction) that transforms your raw training data into meaningful, actionable intelligence to guide every step:

Phase 1: Assessment

Pinpoint your current performance ability and training stress tolerance

FitLogic is the only technology that pinpoints your current performance ability and training stress tolerance relative to your age, gender, genetics, and fitness level. Your training is designed specifically for you.
 

Establishes your Dot Score performance baseline on a 1-to-100 scale normalized for age, gender, and training environment

Creates your Training Stress Profile—your unique fitness fingerprint that quantifies your ability to absorb different types of training stress

The starting point of any quality training program: knowing how much and what type of training stimulus can be applied

Phase 2: Prescription

Dynamically prescribe the right training at the right time

FitLogic is the only technology that knows how much, what type, and how often you should train. We're not relying on training theory or someone's philosophy. We dynamically prescribe just the right training to deliver your best results in less time with fewer injuries.
 

FitLogic dynamically adapts your training as you progress based on proprietary data-driven insights rather than theory or philosophy. FitLogic proactively prescribes training instead of relying on reactive metrics like HR and HRV that show a response to something but don't identify the cause of the response nor the best path forward.

Normalized Training Stress (NTS) proactively quantifies the training stress (stimulus) associated with each workout that you're prescribed and the amount of stress associated with each stress type (aerobic, threshold, muscular, and neural) because not all stress is the same.

The system then prescribes the precise type and amount of training stress that is most beneficial for you considering your stress tolerances and proactively planning for the post-workout recovery time and Residual Training Stress (RTS) (or lagging fatigue).

With EnviroNorm, your training intensities are specific to your training environment. If you change your workout from an indoor trainer ride to outdoors in the heat, then your training zones are changed accordingly.

This delivers the right type of training at the right time to drive consistent performance gains without excessive overload or undue injury risk. You cannot manage or optimize your training if you can't quantify it. FitLogic is the only technology that accurately quantifies training stress.

Phase 3: Evaluation

Meaningfully evaluate training progress beyond vanity metrics

FitLogic is the only technology that meaningfully evaluates your training progress and response to it. No more vanity metrics like accumulated distance or duration. How you train is far more important than how much you train.
 

FitLogic's TrainX Scores evaluate how well you execute prescribed training—quality over quantity. For example, a TrainX Score of 95+ means you nailed every aspect of the workout (pace, power, time, etc.), while a score of 60 means significant deviations that affect training effectiveness.

Residual Training Stress (RTS) measures the residual effect of your training based on intensity, duration, and frequency, among other factors. It's a measure of the lingering stress from your recent training and is essential for both measuring training response and planning future sessions.

Knowing your specific RTS by stress type is essential for prescribing the right future workouts for you. Without FitLogic and RTS, you have significantly higher likelihood of performance plateaus, injuries, and illnesses caused by overtraining.

How you train is far more important than how much you train.

Phase 4: Prediction

Predict race outcomes and optimal pacing strategies

FitLogic is the only technology that predicts race outcomes based on your fitness and the terrain and climate of the event ensuring you're fully prepared and have spot-on pacing. The better you can predict race day, the better you're able to prepare for it.
 

The better you can predict race day, the better you can prepare for it.

FitLogic's RaceX (Race Execution) runs sophisticated simulations to predict your optimal target race paces and race-day splits considering the local terrain and environment (temperature, humidity, and elevation). You can export your optimized bike power plan for spot-on race day pacing.

FitLogic is the only technology that actually predicts and evaluates the outcomes of the training it prescribes. It's the only technology that can evaluate and improve its effectiveness to help you realize your performance potential.

The Difference Is Data-Driven Training vs. Philosophy-Driven Training

Traditional AI fitness apps

Rely on language models trained on internet content about training theories and philosophies—essentially automating someone's subjective coaching opinion at scale.

FitLogic

Transforms raw training data into wisdom through a complete data science pipeline built exclusively for endurance athletics. Every recommendation is backed by objective evidence from real training outcomes.

The Result

Better performance in less time with fewer injuries—because you're training based on what actually works, not what sounds good in theory.
