You typically add 1-2 minor assistance exercises to the workout for 1-3 sets of 10, e.g., back extensions.The third training day is a moderate day where you use weights that are around 10% lighter than the heavy day. The next training day is a light day that uses around 15-20% less weight than on the heavy day. One day is a heavy day (using 80-85% of your 1RM).Training the same 3 big lifts 3 days a week.3 big lifts per workout (squat, power clean, and bench press in the original plan).While there are several 5x5 set/rep systems, most true 5x5 systems originate from Bill Starr's approach. Heck, even Mark Rippetoe's Starting Strength is a lower-volume version of the 5x5 system. It was the cornerstone of Reg Park's training (Arnold's idol), but it was first popularized by Bill Starr with his book, "The Strongest Shall Survive." Few programs are as mythical in the strength training world as the 5x5 system.
