Workout undergarments...

So I was recently asked what kind of panties I think wouldn't ride up during a workout. I wear two different styles; one being a high cut brief and the other a boy short. I recently wore the boy shorts to a Zumba class and I probably will never do it again. They rode so high....yeah I'm not even going to go there, lol. So this is what I ask, please leave you're comments on what you think works best or what you've heard works best so maybe we can discover the ultimate workout undergarments. Oh, and feel free to leave advice on bras as well!
