The Gridlines builder: a training program open in the spreadsheet editor, with a day expanded in the detail dock

Build, deliver, monitor, and sell your programs.

The program you write guides athletes in the app, returns completed training for you to review, and can become a product you sell, without rebuilding it in another tool.

Build

Build in a familiar spreadsheet-style editor, then deliver the same program directly to athletes.

Monitor

Review completed sessions, compare prescribed and performed work, and follow volume, RPE, and top-set trends by athlete.

Train

Athletes open the app to today's session, log every set, and it flows back to your builder.

Keep the speed and freedom of a spreadsheet. Add athlete delivery, monitoring, and AI without rebuilding the program in another tool.

Built by software engineers with 10+ years at companies like Apple, working side by side with Olympic-level coaches.

Build once. Coach from the same program.

Work in the spreadsheet-style editor you already know. An RPE 8 prescription can become an athlete-specific weight recommendation in the app. The completed set returns as intensity you can track over time.

Prescriptions athletes can act on

Percentages, velocity, and RPE become guidance in the app. Completed work returns to you for tracking and adjustment.

Build by conversation

Connect your library to Claude, or any assistant that supports MCP, and describe the block. It lands in the builder, attributed and undoable.

Publish and sell the programs you already built.

Publish a finished program to a page at your own handle, one-off or as an all-access subscription. Tracked links tell you which channel actually sells.

Your storefront, your handle

A public page buyers land on from any link you share. No website to maintain, nothing to embed.

Paid out daily

Stripe Connect settles sales straight to your bank. Keep 100% of every sale on a plan; 5% goes to Gridlines without one.

Programs go straight from the builder to the athlete app.

Every program you publish lands in the Gridlines app, today-first. Athletes open straight to the session in front of them, log each set as they lift, and it flows back to your builder.

Rosters, messages, and community

Teams and athletes organized in one place, messaging beside the training, and community spaces where athletes post with a logged session attached.
