@tim316 Buy the whole set - there are some crazy ideas in there. The conditioning, the martial arts stuff as well.. good entertainment for sure.. and very down to earth..
The man had an insane work ethic and seems to have tried every form of strengthening himself mentally, physically from east to west..
@jim_68 Congrats on your accomplishment. I, on the other hand choose not to make my workouts too long for fear that I'll "dread" exercising and quit doing it. I plan to keep things short, simple, and stick with it for life.
I chose 12/16 because I wanted to shoot for 1000 non stop and wasn't sure if I'd be able to shoot for that if i went higher.
If you see D2 & D4 i didn't make much progress doing the 16. So i decided to work with the 12 and get to longest continuous swings.
That then helped me make a lot of progress with the 16 in the end.
I've been sedentary long enough that i feel I've already earned whatever tools i need that make it fun for me to get and stay fit - i have an 8, 2x12, 2x16, 20 and a t-handle that goes upto 40kg.
