Betsey Johnson is known for injecting her energetic, playful sense of style to everything she touches, and now the quirky designer is bringing that signature aesthetic to a new activewear line.

Betsey Johnson Performance is a collection of fitness clothes full of bright colors, fun patterns, and punky details that will make you want to hit the gym—stat. The collection was inspired by Johnson's fall/winter 2013 runway show, BJ Loves Kicking A. "I'm so excited about the collaboration for the new activewear collection, which I feel has the perfect mix of performance, prettiness, and punk," the designer says. Included are leggings, zip-up hoodies, shape wear pants, and T-shirts with features such as heat-retaining fleece and gripping tape, and of course, some peplums and bows.

The Betsey Johnson Performance line ranges in price from $49 to $120 and will be available this month on See more of the styles below, plus check out some must-try fitness trends in our gallery!
