As I work to make weight training a part of my fitness routine, how do I make sure I'm not overtraining? Are there some general principles to follow, or signs my body might give me, that I am overtraining? I certainly don't think I'm overtraining right now, but I still think it's something for me to be cautious of. One could, I suppose, recommend some well-defined routine that would be effective at building strength at a reasonable rate without overtraining, but since everybody's body is different, I was wondering if there are some ways of knowing that I am overtraining and need to take it easier or, on the other hand, not overtraining even when I might suspect I am and, in that case, I should feel free to maintain if not increase how frequently I'm training.
