About this coach

What’s in the vault

The coach answers from a retrieval-augmented knowledge base built from two sources:

• Power Punching Blueprint(PDF) — 15 chapters on power mechanics, the four phases, kinetic chains, shearing force, hand wrapping, bag work, and per-punch breakdowns.
• Punch Doctor YouTube transcripts— 98 of 99 videos, roughly 1.2M characters of transcript ingested. One video failed to fetch (subtitles disabled on the source).

The ingested sources are distilled into six synthesized note types: 100 concepts, 37 techniques, 12 phases, 73 fighter profiles, 42 drills, and 23 injury-prevention notes. The fighter roster spans boxing, muay thai, and MMA — it feeds the Style Finder as well as the coach. Each note is cross-linked, so a question about the jab can surface the Jab technique page, the Hip Rotation concept, the Four Phases breakdown, and the Canelo fighter analysis in a single retrieval.

How retrieval works

When you ask a question:

1. The coach decomposes your question into sub-queries — so “compare Canelo’s jab to Crawford’s” becomes two separate retrievals instead of one fuzzy one.
2. Each sub-query runs vector search (semantic similarity against embedded chunks) and graph traversal (following cross-links between notes) in parallel.
3. Results are reranked for relevance and passed to Claude along with a system prompt that enforces Alex’s methodology — not generic boxing advice.

The coach is instructed not to cite video titles or course chapters by name — the goal is to teach the mechanics directly, not to namedrop sources.

Known limitations

The coach has blind spots. Better to name them than pretend they don’t exist.

• No women’s boxing.Zero women’s fighter profiles in the vault right now. Claressa Shields, Katie Taylor, Amanda Serrano — the coach will give you general mechanics, not specific analyses.
• No amateur / Olympic content.The source material is pro-focused. Headgear, point scoring, and amateur tactics aren’t covered.
• ~73 profiled fighters — but not every name. Ask about Tszyu or Benavidez and the coach falls back to general principles. It won’t fabricate a fight analysis.
• Nutrition, weight cutting, cardio programming. Not Alex’s focus. Expect general-knowledge answers, not Blueprint-backed ones.
• Clip Review works on short clips, not live video. Upload a short clip — best filmed side-on, one punch at a time — and it samples up to 80 frames (as dense as ~30fps on a 3-second clip) to score the four phases and read hip-vs-shoulder-vs-hand sequencing, with a pose skeleton drawn on each frame. It can’t watch a live feed or a full sparring round, and accuracy drops on long multi-punch clips where each punch gets fewer frames. When it misjudges a score, your correction calibrates future analyses.
• Defense as a standalone topic. Defensive fundamentals show up inside fighter analyses (Mayweather, Bivol) rather than in a dedicated cluster.
• New videos lag.Anything Alex has posted since the ingestion run isn’t in here yet.

Where mistakes can still happen

Even on topics the vault covers deeply, a retrieval-augmented coach can drift. On internal evaluations, the coach is accurate ~95% of the time on questions drawn from the Blueprint — but that means ~1 in 20 answers still misses a nuance. Use it like you would any coach: a force multiplier, not a replacement for a real one.
