Blacksmith

Always Free • Unlimited

Unlimited free imports. Instant. Coaches who use the Crucible template format give their athletes a premium import experience at zero cost.

Three Reasons to Switch

Instant Import

No waiting. The template format reads directly into the app. Your block loads in under a second.

Always Free

Unlimited imports. Free backfill. No Pro subscription required. No daily import limits. Every athlete gets the full experience.

Perfect Accuracy

No interpretation, no guesswork. Every set, rep, RPE, and load lands exactly where your coach wrote it.

Coaches Program. Athletes Train.
We Stay Out of the Way.

Coaches shouldn't have to learn a new platform to deliver programming. Athletes shouldn't have to reformat a spreadsheet to use an app. Blacksmith templates are standard spreadsheets with a thin layer of structure. Coaches keep their workflow, athletes get a seamless experience, and nobody wastes time on technology that should be invisible.

We built Blacksmith because we believe the best coaching tools are the ones that disappear. Your coach writes the program. You train. That's it.

Three Steps. Zero Friction.

1

Coach Builds

Your coach programs in the Crucible template format, a standard spreadsheet layout in Google Sheets or Excel. Same workflow, structured columns.

2

Athlete Imports

Open Crucible, tap import, pick the file or paste a Google Sheets URL. The template is detected automatically. No settings to configure.

3

Train Immediately

Your block loads instantly with correct structure, training schedule, and optional logged results. Open the app and start lifting.

What's in a Blacksmith Template

Pivot Layout

Days as rows, weeks as columns. Each day lists exercises vertically. Natural for coaches who think in weekly progressions.

6 Columns Per Week

Sets, Reps, RPE, Load, Act. RPE, Act. Load. Covers prescription and logging in one sheet.

_crucible Sentinel

A single row marks the file as a Blacksmith template. Contains version, weight unit, and the training schedule.

Training Schedule

Weekday mapping built into the sentinel row. Crucible places each session on the correct calendar day automatically.

Flexible Loads

Numeric values (225), percentages (75%), and ranges (145-150). Coaches write prescriptions the way they think.

Backfill-Ready

Act. RPE and Act. Load columns let athletes log in the sheet. Imported results populate history, detect PRs, and build the Hall of Fame.

Your Athletes Deserve a Real App.
You Shouldn't Have to Build One.

Starting out as a coach is hard enough without figuring out how to deliver programming. Most new coaches spend hours building spreadsheet templates from scratch, wrestling with formatting, and hoping their athletes can actually read the result. Blacksmith eliminates that entire problem.

Copy the template, write your program, share it. Your athletes open it in Crucible and get a clean, purpose-built training interface (daily view, set logging, PR detection, progress tracking), all from a spreadsheet you wrote in 20 minutes. No app to build, no platform to learn, no subscription for your athletes to pay.

Built-In Client Experience

Every athlete who imports your template gets Crucible's full training UI: Today view, set logging, PR detection, and progress history. It's a coaching app without the overhead of building one.

Skip the Blank Page

Don't know where to start? The Blacksmith template has the structure, columns, and schedule mapping ready. Focus on the programming, not the formatting.

Free for Everyone

Your athletes never pay for imports. Unlimited Blacksmith imports, unlimited backfill, no daily caps. Lower the barrier for every client you onboard.

Start with a Program. Or Build Your Own.

Pick up the free 4-week program and train it as-is, or open the Workshop and craft a block from scratch. Either way: Crucible-native spreadsheet, zero cost, one-tap athlete import.
