Manfred Hoeberl (born 12 May 1964) is an Austrian former strongman and powerlifter who was known as having the largest arms in the world during the early-mid 1990s. Hoeberl was born in the same town as bodybuilding legend and former Governor of California, Arnold Schwarzenegger.
Hoeberl won the Europe's Strongest Man Competition twice (1993, 1994) and was runner up at the 1994 World's Strongest Man competition. Hoeberl competed in the World's Strongest Man finals in 1991, and 1993 as well, finishing 8th, and 4th respectively.
Hoeberl won Austria's Strongest Man 7 times, from 1989-1994 & 1996.
In the early 1990s Hoeberl claimed to have the largest arms in the world. At the 1994 Arnold Schwarzenegger Classic, bodybuilding journalist Joe Roark measured Hoeberl's upper arm to be 25.75 inches (654 mm) cold. Right after Hoeberl curled a 150 lb. dumbbell for several reps and was re-measured at 26 inches pumped. After the measurement Roark claimed Hoeberl was the first man in history to have an upper arm girth three times the size of his wrist circumference.
