Recruit your kiddos and some of their friends (or yours) to play a game of balloon volleyball, manhunt, tug of war, or sock tag (grab the sock hanging from each other’s pockets). Pick out cool prizes, like a visit to the zoo, for the winners! Or, if your kids are into video games, play Kinect Training, Zumba Fitness, or Wii Fit to get you all moving and grooving.
