Are you guys able to do ur prenatal works? For some reason I can't do mind, I wake up everyday telling myself I will start today but it doesn't go beyond. I even bought a prenatal workout DVD from Amazon but it's just sitting on my table. What can I do to build up the courage to actual do at least 15mins a day?
