How to use this
This tool gives a practical estimate. Use it to make better training decisions, then log the actual work. The log matters more than the calculator.
Track the work without the noise.
Another One gives lifters routines, PRs, progress photos, StrongLifts 5x5, and a clean log that stays out of the way.
