That's not to dismiss the importance of adequate recovery.  However, the concerned is misplaced, and tends to lead to rather absolutist positions grounded in nothing more than one's opinion.  For instance, I recently on the interwebs and read on a comment thread about strength and conditioning for jiu-jitsu that you should not squat more than once per week.  Cannot be done because you will not be able to recover.  And I have to say, I agree with this.  Well, I mean, I did agree with the notion that a person cannot squat more than once per week and train jiu-jitsu.  Well, that is until, you know, I actually tried to squat more than once per week.
