Manfred Hoeberl (German: [ˈmanfrɛt ˈhøːbɐl]; born 12 May 1964) is an Austrian former strongman and powerlifter who was known as having the largest muscular arms in the world during the early-mid 1990s.

[2] Hoeberl won the Europe's Strongest Man twice (1993, 1994), the World Muscle Power Classic twice (1993, 1994) and was runner up at the 1994 World's Strongest Man competition, narrowly missing the title to Magnús Ver Magnússon by 0.87 seconds in the final Atlas Stones event.

At the 1994 Arnold Schwarzenegger Classic, bodybuilding journalist Joe Roark measured Hoeberl's upper arm to be 25.75 inches (65.4 cm) cold.

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.

Shortly after the 1994 World's Strongest Man contest, Hoeberl was involved in a near fatal car crash in which he broke several limbs, and fractured his hip in 8 places.
