only americans seem to fall ill with these mysterious exercise related illnesses. my parents were both triathletes, im a judoka who used to run 30km a week and swim 2km across a cold lake, including biking everywhere and going to the gym on my work breaks. i did calisthenics at all hours of the day. i have never come down with a muscle disorder even after training to the point that i was pissing blood.
