The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
You can do mobility stuff in the morning or at night. Before/after working out during warm up or cool down.
Improving position is the first step in getting those muscles to start firing correctly. Keep working with it.
Getting the scar tissue broken up will help free up the muscles. I used a voodoo band and had someone manually work on scar tissue from a puncture wound in my calf. It made a huge difference.
