You know its funny you say that because i was thinking of a second squat day on Friday (back day) because usually finish fast. Like hit some dynamic box squats, in addition to my normal squats on Tuesday. Im still tweaking my program, so im always looking for new stuff.
To me its all about power, but i like hypertrophy on upper body.... its weird.
I guess i like the feel of being strong, and the look of being muscular up top.
