I feel quite squeamish just thinking about what she has done whilst carrying a child. Given her level of fitness, I would expect nothing less than her child turning out to be a superhero with special gymnastic powers!  

Weight lifting when pregnant is insane.  But only if unassisted.  I weight lift solo mostly with a machine but sometimes with free weights and when using free weights  I'm always conscious that I might slip and cause a bad injury.  It's a small risk but a risk none the less.  The potential risk to a baby is obvious.  Looking at the weights in that picture, those are big weights and a small slip could be fatal to her child.  My initial thoughts are that she's a moron but the picture may just be for show.  It depends on how much assistance she has when weight lifting if it is a danger to her child.  The assistance can never be 100% so it looks to me like a risk that isn't worth taking.
