Okay, perhaps not for communication but for injury prevention and my own personal rehap....it is the best.
I did look at the general instructions initially and through trial and error I have found my own trigger points and sometimes it hurts so good! This is when I know I need to keep foam rolling!
My problem child is my left piriformis muscle and although I seem to be doing okay with it and the foam roller, I always am looking for ways to be more effective. I have found a good video demonstrating good form for using the foam roller for your piriformis muscle. I tried his tips and it made a huge difference in a quicker release --- and isn't that what we are after?
Jai's advice was so helpful on my glutes I thought perhaps I would look and see what he suggested for my hamstrings to see if it was equally helpful. And yes, sweet success! The tips he provided were quite useful to how to better position myself for one leg, to straighten my back more, and how to alter the effect with toe placement.
