What muscles are stretched using the Back2Life massager? Is it just the lower back muscles or also the piriformis and gluteal muscles?
It's OK, not a cure, but it helps me. I've had it for 4-5 months. I don't use it as much, but when I hurt any help is appreciated. I think more consistent use might be better. Generally I do feel better even the next day. I should use it more. (07/18/2010)
