You can google “workout recovery” and lots of info will pop up.  Every good and smart athlete takes their weeks off, in a year most will take a month or more off.  Most of the aches and pains are accumulations of micro injuries that happen during training that for the most part could have been prevented with a intelligent training program.  Learning how to properly breathe, de-stress, get enough sleep, do recovery exercises, and nourish your body are all super important parts of overall health.  For some reason few want to engage in proper training, most just want to train constantly; just ignoring, or not even being able to listen to what their body tells them.  Some people see the light and some don’t.  The right thing to do is to promote and instill recovery into our routine.
