Corsa builds a personalized weekly training plan for running, road cycling, mountain biking and triathlon — and explains every workout in plain language. Training for your first 5K? Is your 12-year-old starting NICA this season? Corsa adapts to both, with more conservative safety rules for young athletes built into the engine.
Corsa generates your weekly training plan with an AI agent grounded in a curated knowledge base of coach-approved workouts. The mobile and web apps adapt the interface to your level — beginners see effort, advanced athletes see power and pace.
Your next week’s plan lands every Saturday morning so you can see what’s coming. The plan respects your schedule, sport mix, and goal.
Every workout explains what it builds and why it’s in your week. No jargon required — “Easy 45-min ride that builds your base without adding fatigue,” not “Z2 / 45.”
Hard caps on how fast training grows, how much of it is hard, and how often athletes rest — more conservative for young athletes. The AI writes each week’s plan; our code checks it against these limits before it reaches the athlete, and no setting turns them off.
Skip a session, get sick, or change your week — tap “Adjust plan” and your plan rebuilds. Tell it why, and the AI uses that context.
Syncs with Apple Health and Strava so your real activities feed back into next week’s plan.
Just starting? You see Easy / Moderate / Hard. Experienced? You see HR zones, pace targets, and power. Same engine, different interface.
The plan, the “why,” and the rebuild flow — together in one app.
Young athletes new to training get at least two full rest days a week, a lighter recovery week after every three weeks of building, and never more than 10% more training than the week before.
Workouts are described by how they should feel — not pace or heart-rate targets — until an athlete is ready for them.
Accounts for 7- to 12-year-olds stay locked until a parent verifies. Parents can review, pause or delete at any time.
