Whether it's Michelle Jenneke's starting line warm-ups or the geek goddess, April O'Neil, doing push-ups, these babes working out in GIF form are just too hot. When we say April O'Neil is doing push-ups, she might not be fully doing ones, but we're just fine with that.

Michelle Jenneke caught a lot of widespread media attention with her adorable, yet extremely sexy, pre-race warm-up dances, so we decided to throw her into this collection of fit babes execising. While not all of these GIFs are exactly workout pictures, the sexy ladies in them are still being active and are exercising to some degree. So be prepared to get your swell-on with these GIFs of fit babes working out.
