These are the workout pants I've been looking for my whole life (I just didn't realize it until I chanced upon it on Amazon...) They're comfortable, sleeky, and sexy. I do interval training, weights, plain ol' cardio, and stretching all in one go, and want workout gear that can keep up with everything. These pants not only hug the thighs, but also most of the calves, so you don't have to worry about pant legs swishing back and forth while you're jumping all around. It also goes up to just a little below the belly button. Like the previous reviewer mentioned, both the belly and butt support is great. (I tried folding the band down for a low rise look, but that didn't work out too well.)

As for sizing, I'm almost 5'7'', 130 pounds, a size 6 in Juniors, and ended up getting a M. The S was too tight to feel comfortable while exercising. Note that I'm normally a S in Champion workout gear. If you're unsure about sizing, I'd highly rec getting two sizes and just returning one later.

Can't rec these pants enough!
