For Strength and/or Hypertrophy Layers I have been doing Rows for Back and Preacher Bench work for Bis all on my high pull days. Normally one HDL Normal Layer of 4 sets for back and 3 HDL Normal sets and and 3 Max Reps HDL sets for bis.
@orange: Actually I’m not. The above is one of CT Back and Bi Protocols for the Layers. I’m just revisiting it and making sure new proto has not been initiated. And the posts purpose is make sure the assistance work will not cause over training for the basic layers. But thanks for your wisdom. lol
