Parks are often a great place to find free classes around you. New York city isn't the only place that has these and there's more than just these exercises. Meetup.com and other websites offer a great way for people to get together for all sorts of fitness activities which can be very cheap or even free in many cases. Other than classes like this, jogging, power walking, and hitting the monkey bars at your local play ground are great ways to use your local environment.
