This 4 week block is what some would call " building an aerobic base", would this come under GPP? my group has just come off of our month off a few weeks ago. I was going to include cleans after this 4 week block, do you think i should add them as another excercise or drop the deadlifts and replace them with cleans? my coach last winter made us replace deadlifts with cleans after the first 4 weeks.
