Failing to recover after an intense workout is one of the most common mistakes among newbies. Judging by the guides over www.muscl.net, your body will always be over-trained if it does not have enough time to rest. This is far from the ideal state you want the body to be in. Moreover, muscles grow when you relax and rest, not when you actually workout like if there is no tomorrow. Other than that, failing to rest will lead to various injuries overtime, not to mention about an obvious state of exhaustion. At some point, you will not even be able to workout.
