Liftin'

Liftin' is a strength-training tracker for iPhone, iPad, Mac and Apple Watch, built around proven programs and automatic progression. This connector gives Claude access to the training data in your own Liftin' account, so you can analyze your progress and shape your plan in conversation. History and progress: read your workouts with every logged set, follow how specific exercises are progressing across workouts, find personal records, and compare volume or frequency over time. Programs and routines: see which programs you are running and which routine is up next, read any program's full plan, and have Claude build a new program or standalone routine, following a template like 5x5 or 5/3/1 or your own design, with sensible starting weights taken from your history. Editing: adjust planned sets, rep targets and weights, add or remove exercises and supersets, update training maxes, set rest timers and exercise notes, and turn on automatic progression rules so the app keeps adjusting your weights and reps on its own. Claude presents every change and asks for your approval before applying it, and every change syncs to your devices through iCloud like an edit made in the app. Exercises: search the built-in catalog, browse everything by muscle group, and create custom exercises when nothing matches. What it does not do: start or log a live workout, or delete workout history. Logging stays in the app and on your wrist. Requires the Liftin' app with iCloud sync turned on. You sign in with the Apple Account your Liftin' data lives in. Apple's sign-in session is time-limited, so Claude will occasionally ask you to sign in again.
