These shorts really help you work up a great sweat when exercising; I love them so much I bought a second pair just a few days later. I now wear them every time I work out and I love that they are not only very comfortable, but look pretty stylish too. The quality is great; I've done hundreds of deep squats, lunges, and stretches in them and haven't had any problems with the seams holding up. The only thing I don't love about them is that, since I have a smaller waist for the size of my thighs, they are kind of loose in the stomach--but I guess they need to be so that you can still move around freely. Overall, I am extremely pleased with these shorts and highly recommend them.
