Will you be working at home, at the gym or the Y? You can do something different at each place. If you can see a personal trainer for a visit or 2, or if you go to the gym or Y where someone can introduce you to the equipment, that would be great.
Home you can use gallon jugs for weights, dance while sweeping, do situps holding water bottles, pushups (vertical on the wall, etc). Ideally, eventually you will get somewhere with "real" gym equipment
