Yes good but ....

Came across this role on the Internet. Make a lot of sports and use them to support. You can really solve tensions so eg before and after a strength and endurance training. At the beginning I made a mistake! I had arge back problems and back at my first exercise on this role has come up with a loud noise my lumbar put right back! That should make only a doctor. So you should check in advance whether you have some aches and pains that should be clarified in advance by a physician. Otherwise, I'm really satisfied with the role.
