I got myself the Blackroll after I have it with my brother, professional ice hockey player, and with a friend, a physiotherapist, both seen and tried. Both assured me that the initial pain (and it does really fucking hurt) over time although a little better, but after using the Blackroll one is as free ... and yesterday, after the first attempt, I realized after a significant relaxation of all "rolled" muscle ... especially the back and the outside of the thighs is really not painless at first, but then just a great feeling. I'm curious how it will work after a training session is the muscle or fascia. In addition, you can use the Blackroll well as exercise aids and various strengthening exercises moor so, I have to find a lot of videos on Youtube
