HOW: Start in a standing position. Slowly begin performing jumping jacks in place at your desired and comfortable pace. In terms of jumping jack form, you start with a jump in place as your arms go overhead and your feet spread apart, then you jump again and your arms come down by your sides and your feet come together. Repeat
FEEL: This should feel like a full body workout that will get your heart rate up.
COMPENSATION: Focus on good jumping jack form (see video for tips and details). Stay 'soft' with your impacts to begin, however the faster you go the louder your impacts will be, and that is ok. You should be relatively stiff and rigid throughout your body, don't excessively 'bounce'.
