The physics of fitness,
as an SDK.
Quantify athletic performance inside your own application. Send flat workout data and get back real mechanical work, power and work capacity. Don't just log workouts. Measure fitness.
“Fitness is… your work capacity across broad time and modal domains.”GREG GLASSMAN — FOUNDER, CROSSFIT
Six endpoints. One engine.
Integrate the biomechanical engine directly into your architecture to turn raw data into high-fidelity fitness metrics.
Workout Power
Quantifies true mechanical intensity across multi-modal movements. Applies the engine to flat data — reps, weight, time — normalising disparate modalities into a universal energy currency.
RepMax
The high-force, short-duration ceiling. Analyses isolated maximal-effort sets to identify the high-intensity anchor of the power-duration profile.
Kinetic Work Capacity
Overall fitness across broad time and modal domains. Aggregates trailing telemetry into a unified snapshot of absolute mechanical power — a baseline for longitudinal tracking.
Allometric Power Quotient
True mass-normalised capability. Allometric scaling converts raw mechanical output into a dimensionless scalar, enabling equitable cohort comparison across all body types.
Power Curve
The full spectrum of physical capacity. Synthesises varied workouts to map power decay and fatigue resistance, from one-second bursts to endurance efforts.
Pythia
Predictive time forecasting. Intersects the demands of a future workout with the athlete's established curve to calculate precise completion times.
Move the finish time. Watch capacity recalculate.
