i would just change your split and add an extra leg day...
mon legs.... if you have access to a trap bar use this on this day
tues chest,delts,triceps
wed off, or cardio abbs etc
thurs legs
fri/sat back, traps, biceps
fuck the am/pm shit.. volume low or high, reps low or high is a personal thing, all adds up to the same thing anyway..as for dc, its fun to begin with, but for me it just leads everyone into injury
