Jim Wendler’s Beyond 5/3/1 program appeared for the first time in his new book Beyond 5/3/1: Simple Training for Extraordinary Results. This program’s name is a bit confusing because this program is not really 5/3/1 at all. Wendler and many readers are already excited. Black Iron Beast is staying on top of the game with this new calculator.

Added a 0.75 pound/kilogram plate input.

The bar weight input in the form now allows you to enter any weight. Honest folks using 20 kg bars can enter 44 lbs. Others at freaky gyms can enter 18.7 or whatever.
