What workouts/exercising do you do with your BABY?!
I am a single mom so it's really difficult for me to just be like "OH, MOMMY'S GOING OUT FOR A RUN BBL, LITTLE 5 MONTH OLD CUTIE!"

So what do you do? We all know to bust out the ol' stroller and go for a walk, but seriously! Let's spice it up! I want some good answers, people!
