I did it twice a week, Monday & Friday, something like that. Did it after everything else and found it to work just fine. Ran it for 5 or so weeks and then just stopped. Pain was gone after about a few more days of recovery.
It was fucking gruelling. Turn you into a manly man's man for sure. Can't imagine having to do something similar for a shoulder or hamstring tear or something. That's probably a whole other level of gruesome work. Good luck.
