Training progress graphs in customer portal (per exercise & period)

In the client portal, I want a “Progression” tab where clients view their training progress as graphs, without having to click through per workout. Think of: per exercise (e.g., squat/bench), development of weight, reps, volume, and (optionally) %1RM over time, with filters by period and training plan/week. Extra handy: PR markers, selecting multiple exercises at once, and a clear “adherence/completion” graph per week.
