Girl + Fitness Ball = Epic Face Plant (GIF)
I have one of these fitness balls at home and it is quite amazing to see the amount of exercises that can be done with them. You can use them for push-ups, sit-ups, core workouts, and they can also help improve your balance. However, there is one thing I would advise against when using a fitness ball; jumping on it. And if you are going to use it in such a manner, at least make sure you have a video camera rolling so that we can post the results on here.
