How Brick coaches

Brick separates structure from story. The planning engine decides what lands on your calendar. AI explains why, narrates briefs and debriefs, and chats with you — it does not invent the next workout.

Deterministic first

Season shape, weekly volume, sport split, session placement, and workout prescriptions come from a rule-based engine. Given the same history, prefs, and races, the plan is reproducible and auditable. That is what makes Brick feel like a coach with a method — not a chatbot with a calendar UI.

AI is budget-capped and evidence-driven. It grounds claims in your data and never silently rewrites structure.

The closed loop

1. 1

   History, prefs, races, and limiters

2. 2

   Macrocycle — base → build → peak → taper

3. 3

   Weekly skeleton — longs, quality, fillers, strength

4. 4

   Session prescriptions — purpose, intensity, guidance

5. 5

   You train and sync activities

6. 6

   Readiness, limiters, and load update

7. 7

   Proposals you accept or dismiss

You stay in control

When readiness, missed key sessions, or load suggest a change, Brick opens a proposal — step up, step down, ease the week, reprioritize, rebalance, return to training, or recalibrate. Nothing structural changes until you approve. Details: Readiness, check-ins, and proposals.

Coach voice

• Experienced, direct, warm, and evidence-driven
• No invented numbers — claims tie back to your data
• Detail level scales with your coaching preference (educational → data-dense)
• Training guidance only — not medical diagnosis

What makes Brick different

• Tri-native bricks — long ride + brick run as an atomic pair in build/peak, not two unrelated sessions.
• Capacity from history — volume anchors to what you have actually done, with sensible comeback logic after layoffs.
• Limiter-aware work — detected weaknesses influence which sessions get priority. See Limiters and blind spots.
• Life targets periodized to training— sleep, fuel, and hydration follow the day's load. Fuel, sleep, and recovery.
