Stop guessing why your training isn't working.

KAI Academy is your AI strength coach — connected to your training data, holding you accountable to your goals. Professor Iron sees your last workout, remembers your goals between conversations, and gives you advice grounded in what you actually did.

ASK ANYTHING

- "What should I work on next?"
- "Show my bench progression over the last 3 months"
- "Compare my volume on bench vs squat this month"

WEEKLY CHECK-INS

Set a weekly check-in and Professor Iron reaches out when you said you'd show up — to review the week, talk through what's next, or just keep you on track.

DAILY LESSONS FROM THE LIBRARY

Every day, a new lesson from a 150-fact library covering training science, recovery, programming, and the principles behind getting stronger. Stop scrolling YouTube for advice you can't trust.

WHAT KAI ACADEMY DOES BEST

- Reviews your training based on your actual Hevy logs
- Remembers your goals and adapts coaching to them
- Spots patterns you'd miss across weeks of data
- Answers programming questions with your context, not generic advice
- Holds you accountable through scheduled check-ins

WHAT IT ISN'T

- Not a workout logger — Hevy is best for that
- Not a nutrition tracker — MyFitnessPal or Cronometer for that
- Not an algorithmic program generator — Professor Iron coaches by conversation, not by spitting out a fixed plan

Built on three principles: Knowledge, Adaptive, Intelligence.
