## What is Corpus?

Corpus is a focused strength training log designed to help you track workouts, monitor muscle fatigue, and follow structured training programs.

Log your lifts, follow structured workout “Rites,” and visualise how each session affects your body.

There are no ads, no subscriptions, and no in-app purchases, just a clean tool built for people who care about their training.
