Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the formidable-pdfs domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

1RM Calculator & Load Estimator – MyoJournal

1RM Calculator & Load Estimator

The accuracy of this calculator will vary based on the lifter, lift performed, as well as the reps and RPE of the assessed set. Specifically, the calculator will be more accurate the lower the reps performed, and the higher the RPE of the set. This is simply an estimation TOOL. Its use is at the sole discretion of the user.

This calculator is adapted from ideas originated by Mike Tuchscherer of Reactive Training Systems.
