How It Works
AI Guides. Head Coach Decides. You Execute.
K90 isn't a chatbot pretending to be a coach, and it isn't a downloadable PDF. It's a real system with a real person reviewing your program before it becomes yours.
Build Your K90 Profile
Goal, experience, schedule, equipment, sport, recovery, preferences, and limitations — all in your own words.
K90 Match
Your profile is matched against curated, coach-approved training systems designed for real goals and real constraints.
Program Prepared
A personalized program is prepared from that match — built from proven K90 programming, not generated from nothing.
Head Coach Review
A real Head Coach reviews and approves your program before it ever becomes active. AI never has the final say.
Train + Track
Log every set — weight, reps, RIR — plus meals and steps. This is the same data your Head Coach reviews.
Review + Adapt
Weekly check-ins feed real coaching decisions: continue, adjust, deload, or address something that came up.
Day 90
You prove it with real, logged data — then decide what's next: another cycle, a new goal, or a new season.
