My son was told by the doctor the consequences of playing with a trashed knee. The doctor contributed his condition to his workouts. The coach said he knew all about weight training and workouts. The coach said to my son and me in a smartass way , well just go play golf. Well he did, and the other kids that heard the coach decided the coach was out of control , and left. I am saying that all high school athletic programs should be overseen by a doctor that knows the proper weight lifting and workout procedures to strengthen players. I know right now there are a lot of unsupervised training that will do more harm than good. The doctors aren't complaining, at 25,000 for surgery. Doctors say its usually when kids are taught something wrong is when they often get hurt. These doctors know all about the bad coaches and their practices, but don't know the good ones. Can you figure out why. So yes, the experience of spending time,effort, and money, I do know there are some bad coaches that don't know what they are doing. The doctors just confirm it. Ask questions about workouts to the coach. Go to an orthopedist for a physical and advice. It's well worth the money. Wish I did .
