Years later when Yates won Joe Weider's "Mr. Olympia", he credited Mike's "Heavy Duty" principles for his training. Mike, his brother Ray, and Dorian formed a clothing company called "MYM" for Mentzer Yates Mentzer, also known as "Heavy Duty Inc", in 1994. MYM was based on the success of Don Smith's "CrazeeWear" bodybuilding apparel. The three principals wanted to capitalize on the physically fit lifestyle, which today has gone mainstream. With the blessing and promotion of Joe Weider, the trio manufactured and distributed their own line of cut-and-sew sportswear. Mentzer died on June 10, 2001 in Rolling Hills, California. He was found dead in his apartment, due to heart complications, by his younger brother and fellow bodybuilder Ray Mentzer. Two days later, Ray died from complications from his long battle with Berger's disease.   | colspan="3" style="text-align:center;"| Mr. Olympia
