My usual workout consists of kickboxing and pilates 4 days a week, but this summer I've taken to going outside. Instead of confining myself to working out indoors, I've added a soccer workout routine of 3 days a week. This means my workout attire has also changed...for the better. And...what's a better workout motivation  than a cute workout outfit?...Well, other than getting a firmer butt and abs... I have the next best thing: great looking workout apparel. American Apparel and Rebel Yell both have great looking gear...and they seem to be the choice for many celebrities.  Here are a couple examples of what they carry:
