I don't think overtraining is a problem for most people. I like the example of people who are training everyday like in the army who don't become overtrained. I don't think I could overtrain if I tried! Just make sure you're sleeping well and nourishing the body with plenty of good food.

I am going to perform a little trial on myself and see if I notice any negative or positive effects from training a lot more than I already do. Watch this space......
