An app that does your thinking at the gym.
It learns what you can actually lift and what you're training for, then tells you what to do next: the exercise, the weight, the reps. Logging is one tap, so you can stop planning and just train.
This site is where I write about building it, how the coach works, and the design behind it.
The build,
written down
Back in March I built a proof of concept and lived in it for about a month, just the bare MVP, to see if the idea actually held up in the gym. It did. Since then I've been building the real thing, and writing down each day's work right here. Every glowing square is a day I worked on it.

How the coach works
It learns who you are and decides every set for you. Read it plain, or go deep on the memory, the math, and the architecture.
