Larissa Boyce was 10 when her coach, John Geddert, forced her legs into a split so hard she cried. He pulled her right leg up toward his torso, sending shooting pains through her groin and hamstrings, and he kept pulling. “Racking,” as it’s called, was common practice at the gym, but it was evidently too much for Larissa’s mother, who marched onto the mats and told Geddert to take his hands off her daughter. From then on, Larissa would train under Kathie Klages, a relatively low-key coach with unruly red hair and glasses at Michigan State University’s Spartan youth gymnastics team. Klages, like Geddert, considered herself a dear friend of an athletic trainer named Larry Nassar and sent her gymnasts to him.
