Plan your workouts in Claude or ChatGPT. Log them in the app. TrainShell keeps your program and your reality in sync — the AI does the programming, you do the reps.
Design programs in a normal conversation with your AI assistant. It writes them straight into TrainShell — no form-filling, no builder screens.
Open the app at the gym. Sets, weights, rest timer, notes — fast and offline-tolerant. The app is for training, not planning.
Your assistant pulls your logged sets and notes back in, sees what actually happened, and adjusts the next block. A loop, not a spreadsheet.
