I'm reading "Get Jacked ... Fast" by Christian Thibaudeau (I'll start the program next week) and don't understand the meaning of the routine "back and forth".
How should I do the exercises if I find, for example, 2 in "back and forth"?
Thank you all.
P.S. I had tried to write on this old topic (http://tnation.T-Nation.com/free_online_forum/sports_body_training_performance_bodybuilding/get_jacked_fast_omg), but I think it's close ...
