Like learning to use chopsticks, roller-skating takes patience, dedication, and a particularly dexterous set of toes. Show off how flexible your feet are with today's Groupon: for $14, you get admission and skate rental for two (up to a $20 value), plus two hot dogs and two sodas (a $10 value), at RollerWorld NE in Haltom City (up to a $30 total value).

RollerWorld NE’s skate coliseum harbors floor sailors of all skill levels, giving them an arena to showcase fancy four-wheeled footwork or casually cruise with a glissading partner. Lace up a pair of in-line skates or traditional roller skates and take a smooth spin across the well-waxed surface of the rink. During open-skate hours, customers can glide along hand-in-hand, challenge each other to races, or practice classic roller-skating moves, such as the grapevine, the crazy legs, and the Calvin Coolidge Shuffle. Skating creates an exhilarating high-speed workout: the act of propelling oneself forward and rebalancing exercises the quadriceps, calf muscles, and abs, the perfect way to train for the roller derby or roller running of the bulls. Hot dogs and cold soda at the snack bar help skaters amp up energy levels before they attempt to win stuffed cuddly buddies from the claw-crane game.
