Structured workout planning for athletes
Plan cardio and strength workouts with the help of an AI coach (or without!). Export workouts to Zwift, sync directly to Wahoo, or download FIT files for any device. Built for athletes who already know how to train.
AI Coach
Tell it what you want to train in plain English. The coach creates structured workouts with warm-up, intervals, and cool-down. Remembers your preferences and training history.
Structured Intervals
Build complex interval sessions with repeats (5x4min VO2max, 3x10min tempo). Target power zones, HR zones, or cadence. Proper work/rest structure.
Device Sync
Sync workouts directly to Wahoo. Export FIT files for Garmin, Zwift, and other devices. Your structured workout appears on your bike computer.
Cardio & Strength
Cycling, running, rowing, swimming with zone targeting. Strength workouts with sets, reps, weights, and circuit/superset grouping.
Calendar Planning
Schedule workouts across your training week. Move workouts around. See your plan at a glance.
For Real Athletes
No gamification, no badges. Just structured workout planning for people who understand zones, intervals, and periodization.
About
Fitter is built by an amateur athlete for personal use, now shared with others. This is a tool for people who understand training concepts like zones, intervals, and periodization. Not a fitness app for beginners—no gamification, no badges, just structured workout planning.
