He knew what is overtraining

"I train one body part and hit anywhere around 28 to 36 sets per body part, going heavy, with rep ranges between five and 10 and more than a minute’s rest between sets, four sets per exercise, six to eight exercises. I always try to do at least 3 cardio sessions a week, but some weeks do 5. Swimming is my cardio of choice as it builds muscle endurance and helps stretch your muscles unlike running, biking, stair master, etc.
