Free training calculators
Four calculators for the arithmetic that interrupts a training session: what your one-rep max is, what weight matches a target effort, what goes on the bar, and how to warm up to it. They run in your browser, need no account and store nothing.
For gym owners and staff there is a churn rate calculator, which turns member counts into churn and retention rates.
