You know, you may try the YMCA, they have gyms all over and if you are a member you can generally use your membership at any YMCA facility. Ya might check into that.
Some of the things I do outside a gym are:
leg lifts: Lay on your bed. Put your hands out to steady you. Now keep your legs straight and lift them up and over your head. touch your toes on the bed behind you and hold for a few seconds and then let your legs back down. But let them down slowly! Cuz letting them down slow helps you to build your control. That will help with your lower abdomen and probably some other areas too. LOL, I don’t really get into what everything does.
take a small weight and lay so your arm is hanging over the edge of the bed and your body is parallel to the side of the bed. Now lift your arm up to your hip. Hold it there for a few seconds. then move it out perpendicular to your body. hold it for a few, then slowly let it down to the rest position. Now lift it up, forward this time, parallel to the bed. hold it for a few then move it out to the perpendicular position again. hold it for a few then slowly let it down. (shoulder and back muscles)
