Stand-up paddleboards (SUPs) are the next big thing in the outdoor/fitness world. Like its name suggests, you stand up on a SUP and use a single blade paddle to propel you. The standing requires balance, which works out the lower body, while the paddle stroke exercises your core and arms. Even in this sport's young age, off shoots of SUP racing and whitewater SUPing are starting to gain attention, with races being held across the country.
