The AI training coach built for Intervals.icu users
Adaptive AI training plans grounded in 60+ recovery signals and 5 peer-reviewed periodization models. Reads your fitness, HRV, sleep, and training load — plans your week, adjusts each workout when your data changes.
How it works with Intervals.icu
Four steps from connection to your first adapted workout. Your data stays in Intervals.icu — IntervalCoach reads from it and writes back.

Read your data

Plan and adapt
