Mario Fraioli provides valuable advice on how to keep your fitness level up while dealing with an injury. He suggests rest for major injuries, but for minor ones, finding cross training activities that mimic running, such as pool running or using an Alter G treadmill, can help maintain or even improve fitness. Mario emphasizes the importance of focusing on what you can do, not what you can't, and using the injury as an opportunity to address weaknesses and become a stronger athlete.
