I use Fit Mama, too, and really enjoy the workout. I don't do all the arm stuff with the Kegels, it seems like you can do twice as many if you just sit cross-leggged and do them without fanfare.
It's super-super date, but Kathy Smith has a pregnancy aerobics video that is really good cardio, and some weight toning for arms and legs after. Made in the 80's and very hokey, it even has a 'rap' in the middle of it, which I skip. But the low impact aerobics are great. You just have to get over the bad music and whatnot.
