How often should these be performed? CARS - I understand to be daily. But PAILS/RAILS? I read one post which essentially seemed to say "If it doesn't hurt and you can breather through the 2 minute stretch, you're good" but I was looking for clarity. I'm hoping to hit up a FRC course at some point in the near future but for now I'm turning to you guys. Say for example I'm looking at my hips. I can make it through the 2 minutes etc... Do I do my RAILS/PAILS daily then? Do I treat it like strength training and program X days a week? Appreciate any thoughts.
