Meg Kinnard makes quick work of a maze of heavy weights and intimidating, high tech machines. Her lean muscles flex against the metal. Sweat beads on her freshly shaven head. The 40-year-old appears more like a superhero than a woman fighting for her life, especially as she tries to save others. “If something is going on with your body and your doctor’s answers aren’t satisfying you, push harder,” says Kinnard.
