BUILD
WHAT LASTS.
HY3RID continuously understands your training state, decides what's appropriate next, and gets better at making that decision over time. Not a workout app. An intelligence system built around you.
Static programs fail hybrid athletes.
A single-sport athlete can sometimes tolerate a generic plan. A hybrid athlete — developing strength while running, building skill while conditioning — cannot. The cross-modal interactions are too complex. The recovery demands compete in ways no fixed program anticipates.
It builds a model of you
HY3RID tracks how you respond — not just what you log. Your goals, capacities, fatigue patterns, and individual response curves are maintained across every session, continuously refined.
It makes the training decision
Not a suggestion engine. Not a template library. HY3RID determines what training is appropriate given everything it knows about you today — cross-modality load, recovery state, adaptation targets.
It explains the reason
Every prescription carries a defensible rationale — drawn from your actual training data, not generic programming rules. You know why the system chose this session.
It gets better over time
After six months, HY3RID should know more about you than when you started. After twelve months, more than after six. The system becomes demonstrably more appropriate as the record grows.
Polar HRM
Live BLE connection to Polar heart rate straps for real-time ECG, HRV measurement, and conditioning monitoring during sessions.
Health Connect
Android Health Connect integration imports sleep, resting HR, and HRV history — so recovery context reaches HY3RID without manual entry.
Session Record
Every logged session — sets, reps, load, RPE, timing — becomes part of the model. HY3RID reads your actual training record, not a template assumption.
Readiness Check-In
Subjective readiness, energy level, and soreness are first-class signals — not optional extras. They inform the prescription when objective data is incomplete.
One system. Every signal.
HY3RID integrates assessment, programming, coaching, recovery context, and intelligent guidance into a single adaptive loop — not a collection of standalone tools.
HY3RID MAIN
Your training command center. Readiness, session status, recovery signals, and Leonidas — all in context. It surfaces the right information at the right moment, so you always know your next move.
THE SYSTEM
IN YOUR HAND.
Not a dashboard you check once. A live interface that makes readiness, session execution, recovery context, and intelligent guidance usable exactly when they matter — in the session, between sets, at the decision point.

DAILY READY
DO THE WORK
The intelligence behind the intent.
Leonidas is not a generic chatbot. It is HY3RID's contextual AI coach — built with access to your training record, recovery signals, and the reasoning behind your current prescription. It connects what you did, how you recovered, and what matters next. And it is clear about what it does not yet know.
Progress needs permission.
Recovery is not the absence of training — it is the signal that determines what hard work can build. HY3RID integrates your sleep, HRV, readiness indicators, and prior load before deciding what to ask of you next. Hard days land on ground that can use them.
