The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
Kelly recommends 15-20 minutes of mobility work everyday.
If you have a particular problem area in my case the shoulder, should I be working that area every day with mobility smashing, flossing, desecration?
Yes working on a trouble area daily is fine. In the beginning it can be helpful to have 2 sessions a day working the area. It needs the reminders because you are breaking old habits and creating new ones.
