Prototype A	Wanna have a healthy pregnancy? Walk, swim, bike, practice yoga or weight train. Pick what you enjoy and go! Bit.ly/t4bhealthypreg	“Too casual and of course everyone wants to have a healthy pregnancy and whether they are concerned about it or not they should know that exercise is recommended.” (Physician)	Exercise benefits mom and baby! It can reduce risk of preterm birth, improve oxygen supplies for baby & ease labor. Bit.ly/t4bhealthypreg
Prototype B	Exercise means healthy mom and baby. Walk, swim, bike, practice yoga or weight train daily for a healthy pregnancy. Bit.ly/t4bhealthypreg	“This one sounds a little more non directive. This is more informational to me and A is more confrontational.” (Midwife/nurse)
Prototype A	Belly getting in your way? Don’t skip activity, modify with these month by month guidelines. Bit.ly/t4b2modify	“I am a true believer of #2. But I think for the great majority of people, 1 would be better… we are not accustomed to listening to our bodies. This one would be better for our patients.” (Physician)	Not sure if it’s safe to exercise during your pregnancy? Check out this list and consult your doctor. Bit.ly/t4b2modify
Prototype B	Belly getting in your way? Don’t skip activity, modify by lowering your intensity and listening to your body. Bit.ly/t4b2modify	“You know there are different ways to say it. Like instead of saying “belly getting in your way” belly in your way is probably really going to hit patients where their thinking. I would probably have said it differently I would probably say, “Feel you are too far along in your pregnancy for activity? Don’t skip…. Whatever.” That’s what I would tend to say but maybe belly getting in your way is what patients… really think.” (Physician)
