Likely the most aptly named bodybuilder on the list, Kenneth “Flex” Wheeler had a rough childhood growing up in California but coped with his struggles by focusing on martial arts and weight training. After working briefly as a police officer, Wheeler made his professional bodybuilding debut in 1983 and quickly gained a reputation as being arrogant and overly confident after taking home the first place title at the 1989 NPC Mr. California Championships. The four-time Arnold Classic winner also earned the compliment of his career when Arnold Schwarzenegger said he was one of the greatest bodybuilders of all time.
Involved in a near-fatal car accident in 1994 and forced to start over from scratch at the gym, Wheeler beat the odds again in 1999 when he was diagnosed with kidney disease and left with no other choice but to give up steroids. Officially retiring in 2000, Wheeler wrapped up his competitive career with a third place finish at the 2003 Ironman Pro Invitational before receiving a kidney transplant later that year. Now 50 years old and focusing on his martial arts training, Wheeler is looking out of shape and far less flexible than his early career when he was known as “The Sultan of Symmetry.”
