Records workouts the user has ALREADY FINISHED into their MoveMate history — "log yesterday's workout: bench 4x8 at 80 kg, squats 3x5 at 100", or a short history the user is moving over from notes or another app. Send whole sessions with the sets actually done, up to 20 workouts per call. Not a live tracker: if the user wants to log set by set while training, point them to the workout tracker in the MoveMate app (rest timer, weight suggestions) instead of calling this after every set. Dates: a workout from before the user joined MoveMate is history and may have any date; a workout from since they joined must be from today or the last 14 days. For a future date use create_planned_workout. At most 300 past workouts can be moved in through chat in total; for a longer history or an export file from another app (Hevy, Strong and others), tell the user about the workout import in the MoveMate app instead. Every exercise_id must come from search_exercises or create_custom_exercise — never invented. Each exercise is measured by its exercise_type (from search_exercises); send the fields that type uses: default = weight and reps (most strength work, and bodyweight work with reps such as pull-ups or hill sprints); time = duration only (planks, dead hangs, skipping); time_weight = duration and weight (weighted plank, farmer hold); distance_time = distance and duration (outdoor running, cycling or swimming, rowing machine, SkiErg — anything whose monitor shows distance rather than km/h); weight_distance = weight and distance (farmer walk, sled push); cardio_machine = speed in km/h, the machine level (incline or resistance) and duration — treadmill, stationary bike, stepmill; distance is derived from speed and time. Continuous cardio (cardio_machine, distance_time) is ONE set per session — a 20-minute treadmill walk is a single set of 1200 seconds, not three. If you had to guess any exercise, weight, rep count or date, read the workouts back and get the user's agreement before calling. Safe to retry: a workout already in the history (same date, start time and title) is not added twice. Free accounts can finish 3 workouts in total (in the app and here together); workouts from before they joined do not count. A refusal for that reason says so and must not be retried.
