For me, I'm now 25 days away from my due date and am STILL teaching all my boot camp classes 3 days a week (a total of 7 classes) and STILL lifting heavy in the gym 2 other days a week. Yesterday for example, my other pregnant girlfriend and I did an upper horizontal and vertical push/pull workout consisting of bench press (we benched 115 each), cable squat & rows (90+lbs), chin ups (with assistance...), shoulder presses (25lbs each hand), etc. It was a good workout.
My weight is still static at a 15 lbs gain, but, as I've said before, my belly and baby are definitely getting bigger. I'm expecting that this month I'll probably add a few pounds to the scale as baby gets larger, and I'm totally good with that. Even if it means a bit more body fat for me, I know I'll be able to take it off afterwards.
Overall, being pregnant shouldn't remove you from doing activities you love (*unless you have a true medical issue). Whether it be curling, like Kristie, or high intensity workouts like me in boot camp, I'm a firm believer that being very fit through your pregnancy helps you manage the typical aches, pains and bloating that are expected during this time (for me... thankfully no bloating at all, but I do have my shares of aches and pains every once in a while).
Here's to being a fit pregnant athlete! Go Kristie!!
