Do you have a rest day after the 2nd PULL day? Or go right back into legs on day 8?
Also, are you saying you rotate strength and hypertrophy every other workout?
I used to do a 4 day cycle just like it. Actually, I've gone back into it recently. I really liked it for mass. Your volume looks decent, almost on the high side but your joints will tell you if its too much. I had to lower my volume a bit from lifting heavy. I was also using cluster training which is pretty taxing.
