I don't have a runner's physique. I have short, muscular legs and as such, my thighs rub together. Most running shorts bunch up between my legs as I run, creating an uncomfortable feeling. Also, when I sweat, it looks like I peed myself because the sweat quite obviously starts between the legs and works outward.
I'm not a huge fan of built in spandex shorts, but I have a few and they don't exhibit this problem. I was given some Lululemon running shorts for my birthday(don't laugh) and they actually work very well for this. This isn't an option thought because they are $65 a piece.
Anyone have a similar problem? what is your go to running short that doesn't ride up?
