About a year prior, Kitty and Lydia adopted CrossFit, an intense fitness program focused on strength and conditioning. This regimen includes various exercises such as weight lifting, kettle bells, and battle ropes, often accompanied by a unique vocabulary. They also followed a diet mainly consisting of meat, criticizing those who still preferred traditional workouts like jogging and believed that a bagel could be a suitable meal.

The sisters' commitment to CrossFit not only transformed their physical fitness but also shaped their attitudes, leading them to look down on others who didn't share their rigorous approach to health and wellness. They found a sense of superiority in their lifestyle, setting themselves apart from what they perceived as less dedicated individuals.
