AI generation replaces the current open draft. - Shows plan detail pages with days, exercises, sets, reps, weights, and group labels. ## How it works 1. Open `/trainer/workout-plans` and choose `Create Workout Plan`. 2. Select a client. 3. Choose `Plan by Week` or `Plan by Date`. Weekly plans repeat on selected weekdays. Date plans use a calendar with a separate workout-building modal for each selected date, and each date can have its own workout. 4. For weekly plans, choose a ready-made template or start from scratch, then configure the plan name and `Workout Days`. Date plans use the calendar flow. 5. In the builder, add exercises from the library or choose `Add Exercise`. 6. In the exercise form, enter `Exercise Name`, configure equipment and sets, add `Rest Between Sets`, optional `Notes`, and an optional `YouTube URL`, then choose `Add to Workout`. 7. Select an exercise to edit it, move it, remove it, copy it to another day, or place it in a group. Group controls support `Superset` and `Circuit` blocks, rest settings, labels, and circuit rounds. 8. Optionally enable `Progressive Overload` and configure its mode, interval, increment, and unit. 9. Choose the AI workflow, set the available options, and select `Generate` to replace the current draft with an AI-generated workout. 10. Save the plan. A plan assigned to a client can be assigned immediately or scheduled with a start date; an existing schedule can be cancelled. 11. Open a saved plan from the list to view details or edit it. Editing an assigned plan also supports assigning it immediately, scheduling it with a start date, or cancelling its schedule. ## Options and limits - Weekly training days are Monday through Sunday; the create flow requires a plan name and at least one selected day. - AI equipment options are `Full gym`, `Dumbbells`, `Barbell + rack`, `Machines`, `Cables`, `Kettlebells`, `Resistance bands`, and `Bodyweight only`. - AI split options include `Let AI decide`, `Full body`, `Upper / lower`, `Push / pull / legs`, and `Bro split`. - AI focus options include `Hypertrophy`, `Strength`, `Fat loss`, `General fitness`, and `Conditioning — circuits`. - AI exercise variety is a 1–5 slider. - AI cardio options are `Warm-up only`, `Optional finishers`, and `Dedicated sessions`. - AI units are `kg` and `lb`. - Progressive Overload modes are `Auto (when last session completed)` and `Interval (every N sessions)`; interval sessions are constrained to a minimum of 1, and circuit rounds are constrained from 1 through 20. - The AI session length is optional and is included only when entered as a positive number. ## AI access - Spotter: `builder_read_draft` (read), `builder_find_exercises` (read), `builder_edit_exercises` (write to the open draft), `builder_edit_sets` (write to the open draft), `builder_edit_groups` (write to the open draft), and `builder_save` (write; save, assign, generate, or create a custom exercise).
