Inside your plan.
Your plan reshapes as you train based on what you actually did and how you're feeling — not a fixed PDF written months ago.
01
A plan shaped to your goal
Pick a goal — race, distance, fitness milestone, or "feel better." The AI builds the right block periodization, picks the right paces and intensities, and works backward from your target date.
- Targets the demands of your exact event, not a generic template
- Adjusts weekly volume to the time you actually have
- Adapts to your equipment: treadmill, trainer, pool, trails, dumbbells
- Change goals any time — the plan rebuilds in about a minute
02
Strength and limiter blocks
Your AI coach spots the weak link — bike legs for a duathlon, sighting in open water, long-day fueling for gravel — and slots a focused block to fix it before race day.
- The AI emphasizes the limiters it sees in your training data
- Short focused blocks (e.g. "run bootcamp", "swim technique series")
- Strength and mobility tuned to the demands of your sport
- No surprise breakdowns at the start line
03
Always aligned with life
Travel weeks, work crunches, a new baby, a head cold. The AI rebuilds the plan around you — without losing the through-line to your goal.
- Tell the app today's constraints; it adapts the day
- The AI eases your load when your training stress signals fatigue
- Skip days without breaking the plan
- Chat with your AI coach about anything, any time
