I just finished CTX upper body premix, all I can say is WOW! That one is tough! And I consider myself an advanced & it kicked my bootie! I chose to lift heavier than Cathe but had to lower down after chest.
Here's another vote for 4DS UB. It is longer than some of the other premixes, but when you are through, YOU ARE THROUGH!
