The info on positions seems to imply that the positions to be avoided are forever banned. Is that the case or is there some general guideline like 90 degrees? All the other info re bending and sports is progressive and seems to imply that motion and bending improves. It would be helpful if you gave an explanation rather than refer me to a site that already doesn't answer or address these issues. I'd also like to know any signs that would alert one to a problem while 'engaged' that should alert one to stop .
