[Andrey]

Hello. At me muscles of a back badly hold a backbone, iz-for what vertebra or vertebrae "take off" delivering not only inconvenience but also leading to the various illnesses or diseases which are passing or are taking place at their statement on a place. To me speak, that it is necessary to strengthen them, but do not speak as. I so pologaju, am complexes of exercises for these purposes where they can be found, or the device what can? Thanks.

You at other forum under anybody AndrOP set this question.
I do not think, as here answers will be unequivocal.
And actually at a forum nobody will reproduce exercises.
