Is it OK to rotate between the two excercises during the workout?
Like front squat 1x, deadlift 1x, front squat 1x...
I guess it gives a bit more rest between sets, maybe a sound idea?
And is it OK to do overhead press+squat, bench press+deadlift?
I am very intressted why Hepburn and you like a body part split.
Wouldn't two presses at one day make your tris and delts to fatigued to reach your training potential for the last excercise?
