This is a simple winforms app that allows you to record your workouts, view statistics, and simply evaluate your progress and estimate your working weights (if you do powerlifting or bodybuilding). Contact me if you are really interested in it
Just download the latest release, then unpack and run the "ProgressControl.exe"
See Regression models for estimating RM by MRM and other ones at my RPubs
Use this app to predict your RM!
