Kegel up!

Angela
I just got (actually my husband bought it for my birthday) an amazing kegel exerciser. It's connected to an iOS (or android) application. 
Not only does it help with workouts, it measures your strength and endurance so you can see yourself getting better/fitter/stronger. 
The "mom to be training" takes just 5mins a day. 
Lovelifetoys.com/kegels - it's called the Krush.  It's a bit pricey (luckily we got it from Kickstarter at 50% off), but honestly I can't think of anything more important right now (I'm 6 Months pregnant)
