AI-built intervals, strength blocks, and periodization — synced directly to the devices you already train with.
Training isn't logging. It's architecture. Every interval has a purpose, every rest period a reason. If you can't describe why you're doing a session, you're not training — you're moving.
Fitter was built for athletes who plan their season, not just their week. Powered by AI, designed for the serious amateur who races, competes, or simply refuses to waste a training day.
Create work and rest blocks with power, heart rate, and cadence targets. Nest repeats, add warm-up and cool-down, arrange into full sessions — no templates required.
Describe what you're training for — a race, a fitness goal, a session type — and get a complete structured workout with warm-up, intervals, and cool-down, tailored to your targets and history.
Plan your full season with structured blocks — base, build, peak — and let Fitter distribute intensity across weeks so you arrive at race day sharp, not burned out.
Structured strength workouts designed for endurance athletes — not bodybuilders. Targeted sessions that support your sport without compromising your training load.
Fitter speaks the language of serious training equipment. Sync once, train forever.
Most athletes react. They do whatever feels right, log whatever they remember, and wonder why they didn't perform when it mattered. The athletes who improve consistently don't wing it — they architect every session.
Fitter gives you the tools to do exactly that. Interval builder for precision. AI coach for adaptability. Periodization for longevity. Device sync so it works exactly where you train.
