Train Smarter, Not Harder

An AI coach that reads your recovery and adjusts your training when the data calls for it.

Smart Workouts
AI generates workouts tailored to your power zones, training phase, readiness, and learned preferences.
Recovery Aware
Monitors HRV, sleep, RHR, and fatigue from any connected source — Apple Health, Whoop, Garmin, and more — to auto-adjust intensity or recommend rest.
Goal Focused
Periodized training that peaks you for races — or builds fitness toward any training goal.
Daily adaptation

Your workout, reshaped when life changes

A plan written last week doesn't know how you slept last night. IntervalCoach checks your data before each session — and when today doesn't match the plan, the workout adapts before it reaches your inbox.

Adaptive Actions

Today's signals reshape today's workout.

  • +5 min warm-up
