Have you considered that you are overtraining anterior delts? Doing 11 sets for front delts and only three for rear delts is not only unnecessary but can lead to an injury or at the least severe forward rotation of the shoulder. 19 total sets for shoulders is a bit much for a natural athlete considering the amount of work the shoulders get from benching movements and rowing movements. IMO, if you insist on doing this many sets, at least even it out a bit. What I'm currently doing:
3 sets each- military press, Arnolds, db side laterals, machine side laterals, reverse DB flies, reverse pec Dec. Get in and out in under an hour and use 2-1-2 rep timing. -EK
