Well, there are many places I could go to burn off my fat. Sure I could go to a gym and pay hundreds of bucks to use their equipment. But I purely believe the best kind of exercise is the hardcore ones you do on your own.
Thats why I go to Regional Park in Cerritos. The park is huge. I'll start off running around the whole park for an hour (which is a few miles long). However, to cool down a bit after my job, I'll stroll leisurely to one of the tennis courts and play tennis with a friend. When I'm not in the mood for tennis, I'll work across the whole park and play basketball in one of the outdoor courts instead. Sometimes you can play basketball in the indoor courts too, if there are no activities going on. If I just want to exercise lightly, I can walk around the park, but I would prefer to walk around the huge lake that centers the park. The lake is home to a lot of wildlife, including fish, turtles, and birds.
Sure, this park has no gym, but it's a great place to work out and exercise by running/jogging/walking, playing hoops, or playing tennis. Heck, they even have soccer fields and baseball diamonds if you're into those sports too!
