They all do things differently, have you read Yates beliefs?? But you also have to take into account how much gear they use compared to us, plus they train in the am and sleep , then train again in the pm, but everybody needs time out of the gym to recover. Some guys Ive heard take almost a whole month off during the year, cant remember who it was , Ill try to figure it out. But seriously, do some research on your CNS.
