- Coachbox AI New -

Chat with your athletes' data.

Coachbox AI is an expert sparring partner plugged straight into your Coachbox account. Ask about a workout, a lactate test, a wellness trend, or a full season, and get a critical, evidence-based answer grounded in your own numbers, in seconds.

A sparring partner, not a chatbot.

Coachbox AI is built around one idea: a knowledgeable colleague sitting next to you, challenging your thinking. It uses the Socratic method, asks the right questions, and gives you a direct, evidence-based take instead of generic training advice. No bro-science, no hedging, no filler.

What was trained this week? Give me critical feedback on the last long endurance session Compare this week to the previous one Analyse the training intensity distribution of the last four weeks Why is heart rate drifting up at the same power?
Which races are coming up and how should we build towards them? Plan the next three weeks with a focus on VO2 max Is the athlete ready for a test week? What should I adjust in the current training block? Check the AMPK / mTOR interference between this week's endurance and strength sessions
How do sleep, HRV and resting heart rate look lately? Any signs of overtraining or RED-S showing up? Should I move the next strength session? Does a polarised or pyramidal distribution fit the VLamax profile better? Is the strength plan cleanly sequenced (AA → MxS → Conversion → Maintenance)?

The AI pulls the real numbers before answering.

Knows your athletes, not just endurance theory.

Every answer is grounded in your own data. Coachbox AI can pull up an athlete's workouts, wellness metrics, zones, annual plan, races, notes, and milestones on demand, so you never have to re-explain who you're asking about. Mention an athlete by name, or keep the conversation focused on the one you're currently viewing, and it picks up the context automatically.

Training load & PMC
Zone 2 & lactate
POL / PYR periodisation
Interference effect
Strength periodisation
Fuelling & RED-S

Endurance-first expertise.

The assistant is tuned on the science that actually matters in the field: training load and stress balance, Zone 2 and lactate thresholds, periodisation models like POL and PYR, the interference effect, strength periodisation, hypertrophy and fuelling. It stays strictly in its lane and flags RED-S or overtraining patterns when it spots them.

Always one click away.

Coachbox AI sits in the bottom corner of every AI-enabled module. Open the assistant and it already knows which athlete and what you are looking at, no copy-pasting, no re-explaining. Sessions are saved, so you can come back to a conversation later the same way you would with a colleague.

Your preferences 201 / 2000

PYR-biased. Only push polarised when VLamax is confirmed low.

No lab access. I read thresholds from HR drift and 20-min RPE, not blood lactate.

Athlete-facing section: warm tone, never a 6th training day.

Remembers how you like to coach.

Give Coachbox AI a set of personal instructions once, and it uses them in every new chat. Your sport focus, your preferred units, the language you want answers in, how many hours your athletes typically train, even your coaching philosophy. The assistant can also quietly store useful context you mention in a conversation, so it keeps getting sharper the more you use it.

  • Runs with your own credentials, not a shared key.
  • Sees only athletes you already have access to.
  • Every request is logged and traceable.
  • User preferences stay separate from the system prompt.

Private, coach-scoped, and auditable.

Coachbox AI only ever sees the athletes and data you already have access to inside Coachbox. Every tool call runs with your own credentials, every request is traceable, and your user preferences are kept separate from the system prompt so they can't be used to bend the assistant's behaviour. Your conversations stay yours.

“It's like having a second coach sitting next to me, one that has read every paper and remembers every workout.”
