The late Mike Mentzer was among the few bodybuilders who gave the seven-time Mr. Olympia Arnold Schwarzenegger tough competition on the Olympia stage. He was part of the 1980s Olympia, which is considered the most controversial of all time, and fans also think that Mr. Heavy Duty was robbed of his title. But they wonder what training split Mike Mentzer followed to become a formidable opponent to the bodybuilding goat. Let's take a look at former Mr. America's workout split.

According to Set for Set, Mike Mentzer only trained for five days, and each day he destroyed one of his muscles. On Monday, Mr. Heavy Duty trained chest following with back on Tuesday. Wednesday was determined for his massive shoulder, and on Thursday, he took the soul out of his legs. Friday used to be the last day of his workout split, and he trained his arms.
