In this tutorial, we learn how to do a complete workout in 15 minutes with Joanie. The first exercise is to use a mini trampoline and jump on it for 15 minutes while doing small movements. This is a great cardio exercise that will get the heart pumping. If you aren't ready to do jumps, you can simply move your body from side to side and raise your arms up in the air while skipping up and down on the trampoline. Another great way to do an exercise in 15 minutes is to do hula hooping! The last way to get a great exercise in 15 minutes is to use a video game that gets you up and moving! The dance revolution game will help you exercise with friends and have fun at the same time.
