The best thing you can do for your body is listen.....
take a nap when you feel tired,
stretch instead of a heavy day at the gym,
and allow yourself a day OFF!
Decompress, lay like broccoli, just be happy in sloth mode.
You will feel so much better, and have so much more to offer when you are 100% vs stressed at 65%.
Take some time, then get back on it!
