Six Day Powerlifting Routine

I've established a unique routine for myself and those that I train that is somewhat similar to Westside Barbell's method of weight training. The routine that I run's main focus is to build strength in all muscle fiber types as well as cardiovascular fitness, not muscle-mass:

Standard Rep Scheme: (harder) 3x12 or 4x8 or 5x5 or 6x4 or 8x3 (easier)

ME = Max Effort
DE = Dynamic Effort

Sunday: Deadlift ME/Back day
