Maria Cristina, 73, from Reno, Nevada, who became hooked on fitness after working out with a personal trainer for the first time when she was 69, has become a bikini body champion. She was a college president in both Nevada and California for two decades, and started working out only after her retirement.
Cristina admits that she grew "heavier, slower and more stressed" after turning 50, as her career took precedence over her health and well-being.
