Thinking about joining a gym? Before you put down a hefty chunk of change, step into a Chicago Park District Fitness Center. You can sweat it out at 70 locations throughout the city for free January 7 through January 13. In addition to cardio and strength training equipment they've also got classes. Take spin, yoga, pilates and zumba classes and learn about nutrition. Have kids? They've got family friendly options, too.
If you choose to sign up fees are a measly $30 to $60 for a three month pass, and if you purchase a Gold Card for $80 you'll have access to all fitness centers city-wide.
