Core workflow

Creating programs

The program builder. Week-by-week editable, RPE / %1RM / RIR intensity, reusable as templates, exportable to PDF.

The walkthrough

Four ways to start a program

From scratch — pick duration, days/week, training split, and start building.
Duplicate any existing program (yours or a gym template) and edit it.
AI customize — describe the goal in plain English and Stackd drafts the structure with exercises filled in.
Spreadsheet import — paste a structured CSV from Tools → Spreadsheet import for bulk creation.

The builder, week by week

Each program is broken into weeks, each week into days, each day into exercises. You're never editing "session 12" — you're editing "Week 3, Day 2." Add or remove weeks any time. Mark a week as a deload or rest week in one click.

Per-exercise fields

Sets × reps — fixed or rep ranges (e.g. 8–10).
Intensity — RPE, %1RM, or RIR. Switch the units at the program level.
Tempo, rest, and coach notes.
Superset / circuit grouping — drag exercises into a group.

AI customize Powered by Claude Haiku — fast and cheap. Describe what you want ("8-week PPL for an intermediate lifter prepping for a meet") and Stackd drafts the full week structure. You edit from there. Use it as a starting point, not a final product.

Templates vs assigned copies

The program you build sits in your template library. When you assign it to a client, Stackd makes a separate copy just for them — you can edit either independently without affecting the other. Changes to a client's copy stay with that client. Changes to the template only affect future assignments.

Export to PDF

Hit Export PDF on any program. The PDF uses US Letter, printer-friendly white background, accent swoops, and week dividers with logging columns — inspired by the Jeff Nippard layout. Hand it to a client who doesn't want to use the app.
