Depends on your fitness goals.
Loki's idea was great. Nothing much you can do unless, you know a friend that has a work out room in his/her home or garage.
You may look around the house to see what all you have that can be used as weights. Like, veggie cans, wine bottles, broom stick (for abs) Bricks, blocks, Jump rope, Stairs, heavy chairs that will hold your weight and keep balanced where you can do dips, couch (put your feet on edge and do push ups) etc.......Open your eyes sweet cheeks, explore your own home. Make friends. Did you have a work out buddy at the gym you use to go to? Maybe the two of your can hook up?
Or, simply shop online for equipment. Try Ebay.
