Don't you think what you are doing is more likely to develop a Ronnie Coleman physique than a Jeff Monson one?
I mean firstly Monson was born stocky, he doesn't really have that much extra mass on him relatively speaking. And what he does have was achieved by his type of explosive and strongman training. Don't you think what you are doing is more inclined to induce the wrong type of hypertrophy?
Just my two cents, hell if you are squatting 315 x 6 I see no reaosn to stop what you are doing hah.
