AI refresh of target reps/weight when starting workout from a template

When a user starts a workout from a saved template, allow the AI to automatically update (or optionally prompt to update) the target weight and reps for each exercise based on recent performance history, instead of always using the originally-saved template values. Problem: Template targets become outdated over time as the user progresses, leading to too-light/too-easy starting targets. Requested behavior: - On starting a workout from a template, provide an option to “Refresh targets with AI” (prompt and/or per-template toggle). - AI recalculates suggested target weight and reps per set using recent sessions (e.g., last 3–5 performances), user progression trends, and optionally readiness signals if available. - If no recent history exists for an exercise, default to the template’s saved values (or a conservative suggestion). Benefits/use case: - Keeps templates useful long-term without manual editing. - Reduces friction and improves progressive overload adherence.
