Guinness World Records' geriatric fitness phenoms

Age might only be a number, but the people on this list of record holders take that to a whole new level.

Guinness World Records announced in May 2012 two remarkable records held by two remarkable women: The "Oldest Female Competitive Bodybuilder" and the "Oldest Living Yoga Teacher."

As the newly crowned "Oldest Living Yoga Teacher" in the world, Tao Porchon-Lynch, 93, was fascinated by the activity from the first time she saw it as an 8-year-old living in the French colony Pondicherry in India. After a career in the entertainment industry, Porchon-Lynn embraced yoga at age 73, making it her full-time career. She currently teaches classes four days a week at the JCC of Mid-Westchester in N.Y., where she teaches students everything from meditation exercises to eating habits.
