8-Bit Training

Old-school kettlebell strength. Tiny pixel coaches.

Get the app

Guided sessions, rep-by-rep cues, and a training log that syncs everywhere via iCloud.

Bring your AI coach

The 8-bit-trainer MCP server teaches any AI agent to author complete training programs — exercises, pixel art and all — in a portable format the app imports with one tap.

Share a program

Programs travel as a single JSON envelope. POST one to /save and get back a durable short link with a pixel-art preview — see it in action once you export your first program.

Links are content-addressed: the same program always maps to the same link, and a link never changes meaning.
