Those who have not already mastered the art of contracting
the muscles of the vaginal orifice [Constrictor Cunni) and
those of the interior vaginal passage (Levator group)
independently of one another, should not attempt this during
pregnancy. It will suffice in these cases to give indirect
exercise to the Levator group, by contracting the gluteal and
anal muscles as though controlling an unwelcome motion of
the bowels.
The direct general exercise of the pelvic floor can take
place throughout the whole of gestation, but is of most
benefit, if there is already control and mastery of these
particular muscles, before pregnancy begins, as, in that case,
it is only necessary to keep in training.
