Since there are so many questions on this subject, I've decided to clear some things up. First of all there is no one rule for overtraining. Everyone is different. Everyone's recovery abilities are different. The AVERAGE person needs about 9 days for a muscle group to recover (with the exception of biceps which recover a bit quicker). Most people do not allow enough time for their muscles to recover which leads to plateaus. If you figure out how much time you need for recovery, and you train right, and you EAT, you will continually see improvement. Most people who train have trouble being objective rather than subjective. Instead of analyzing themselves they tend to compare themselves to others. Bodybuilding is OBJECTIVE.
There are a few variables that effect recovery
1) Steroids - If you take steroids, your recovery capabilities will be greatly enhanced
2) Creatine - If you take creatine your recovery capabilities will be enhanced
3) Nutrition - If you are eating right/enough you will take less time to recover and vise versa.
4) Intensity - If you are training with very high intensity you will need more time to recover and vise versa.
