On-Device AI TrainingTraining deserves better thanguesswork.
Science-based programming. Privacy-first AI.
Built for athletes who take training seriously.
Your data stays on your device. Period.
Strenua's AI runs entirely on your iPhone's Neural Engine. No cloud processing, no data monetization, complete offline capability.
Neural Engine
All AI inference runs on Apple Silicon. Real-time analysis without cloud latency or privacy concerns.
HealthKit Sandboxed
Data access is strictly sandboxed. We never see, store, or transmit your raw health data.
Zero Connectivity Required
Train in the basement or on a plane. Your intelligence is in your pocket, not in the cloud.
Built different.
Programming grounded in research, not randomness.
Every session is part of a periodized plan. Progressive overload, volume landmarks, RIR-based autoregulation, and frequency-aware recovery modeling. No random workouts of the day.
Block Programming
Structured mesocycles with accumulation, intensification, and deload phases. Training that adapts to your progression.
RIR-Based Loading
Prescriptions adjust based on your reps in reserve. The AI learns your strength curve and adapts in real-time.
Muscle Recovery Model
Frequency-aware recovery tracking per muscle group. Training stimulus is timed for optimal supercompensation.
What we stand for.
On-Device
All AI runs on your iPhone's Neural Engine. Zero cloud processing. Zero latency. Your data never leaves your phone.
Data Sold
Your training data is yours. We don't see it, store it, or monetize it. No accounts, no tracking, no compromise.
Offline
Train in the basement, on a plane, or off the grid. Full intelligence without a single byte of connectivity.
Autoregulated
Every prescription adapts to your performance in real-time. Reps in reserve, progressive overload, periodized blocks.

& Answers
Everything you need to know about Strenua.
Strenua uses CoreML to process your workout data directly on your iPhone's Neural Engine. No personal health data is ever sent to a cloud server. Your training intelligence lives in your pocket, not on someone else's servers.
Currently, Strenua is exclusive to iOS to leverage Apple Silicon's Neural Engine for our on-device AI models. This isn't a business decision—it's a technical one. The on-device processing requires specific hardware capabilities.
Whatever you have access to. The AI adapts your programming based on your available equipment profile—whether you're in a fully equipped commercial gym, a home setup with dumbbells, or training bodyweight only.
Yes. Strenua reads and writes to HealthKit, seamlessly integrating with your Apple Watch and other health apps to build a complete picture of your training load and recovery status.
Every workout is built on periodization principles: progressive overload, volume landmarks, RIR-based autoregulation, and recovery modeling. No random workouts of the day. Each session has a purpose in your training block.
