I have been reading the new book and am very new at all of this so please excuse my ignorance... I was enjoying the book UNTIL page 139 and beyond. I really do not understand the workouts at all! The only thing I get is the routine set up on page 125 which makes total sense but when I get to page 139 it's like I am reading another language

The charts on pages 140-141 confuse me even more. I really could get everything else up until this point can someone please clarify this I really don't want to have this book go to waste.
Thanks
