Ok so I have been asked to post a few videos of pregnancy workouts. As strange as this may seem I had to wait for several ladies to actually look pregnant. The main thing to keep in mind is that as pressure on your back increases you need to find a way to support your back during exercise. No deadlifts. No deep leg presses. Try to keep in mind that your hips will expand so you should widen your base to accomidate that. Keep very aware of your form and breathing.

One thing I didn't mention before is that it is very important not to undertake any brand new style of working out during pregnancy. Not the best time to run your first marathon. Watch this video and look how she supports her back through the range of motion.
