First of all you train diffrently depending on your goal. Second if you want to be a powerlifter then high rep is a waste of time(more or less) and if u want to get ready for the beach or comp then u should stick with higher reps and more isolation(dont exclude compound tho). Up the volume 20-30% and keep it simple. Trying to set the world record every time you are on the juice will end up destroying your joints, tendons, ligaments and just about everything else.
