After running I did my 'tribute to the psoas' class done by Tiffany on Yoga Glo. The first time I did this class about a year ago it opened up my entire world. A body part I knew little to nothing about was/is a big part of my back pain. Yet,I have neglected to take this class regularly.
Thus...my plan is as follows; every time after I run (at least for awhile) I do my 45 minutes psoas opening class. I hope this aids in recovery and enables me to run more.
