Betty Brosmer – Age: 91 Years

American physical fitness guru, Betty Brosmer, who is later on known as Betty Weider, started her career pretty early. Given credit for her tiny waist and iconic pin-up girl look, she sure is super stunning during her glory days. At the age of 13 years old, she was already in the catalog of Roebuck and Sears. She discovered her love for athletics and physical activities at a very young age and leveraged it to launch her physical body training career. She also began a modeling career and is today believed to be the World’s First Supermodel, which apparently ended in 1961 when she married Canadian bodybuilder Joe Weider.

However, Betty rediscovered her love for fitness and bodybuilding and was frequently featured in fitness magazines. This love for physical fitness led her to have good health at the age of 91. She seems not frail at all and her face seems to be younger than her actual age. To this day, she is recognized as an authority in the health and fitness industry.
