Here's a section from vertical dance on poling and pregnancy, and i think there are a couple of threads for it in health and fitness.
Are You A Student and Pregnant?
If you are new to pole, a student in a class situation or learning from home think about what you are doing carefully and I would recommend stopping
certainly by 20 weeks if not far sooner. For the first trimester you Should be ( that is if your health provider say its ok and you have no pregnant
complications) fine continue maintaining your moves, You should defiantly NOT try out new inverted moves and you should be carful as you will be
feeling many symptoms of pregnancy that make you feel unwell, dizzy and even uncoordinated, while it will generally take a massive trauma too
loose your baby, the first trimester is the time where miscarriage is most likely, so I would advise you take up another form of fitness if you can.
During the second trimester you may start feeling better, how ever your body is beginning to change shape, which means your centre of gravity is
changing, which can make you off balance. Huge changes are taking place, the effects of a hormone called relaxin are coming into effect. Your ligaments
and tendons (amongst other soft tissue) have become soft and loose in preparation for the widening of the pelvis for the birth of your baby. This makes
your joints unstable and you could permanently damage your joints by either lifting too much weight( your body) or over stretching them (hanging
from the pole or over reaching). Laying on your back for a period of longer than 2 minutes can effect blood flow to the baby, so supine floor work
should not be performed. If you haven't given up by now you should as there are lots of different forms of exercise you can take up that will mean
you are less likely to fall.
The third trimester you will start to feel tired again, your carrying a huge weight of baby and boobies and you may be feeling anxious about the birth,
the last thing you should be thinking about is your pole, its only a few more months and you will be back on it so don't worry!!! Doing weight training with
the arms over the head Is really not advised has it effects your blood flow and pole dancing is weight training with either one or both arms above your
head, also you have that big bump in the way, its precious and you don't want to bang it. Your strength will have almost totally left you and you wont be
able to lift yourself into a chair safely let alone a butterfly! Your abdominal muscles are either stretched to the limits or have opened down the centre,
you can not contract them very well as they are stretched so you will find it very difficult to lift your legs to go into an invert. You probably wont be
sleeping well as the baby is kicking a lot, your tummy is stretched so much that you think the baby may burst out and this is no shape to pole dancing
in. If you are then I really think you now have to stop!
