Standing calf raises.
Fly machine that you can adjust to do rear delts.
I lie down on a bench facing the bench. Arms out to the side and do the shoulder rotations. Hard to explain but just alternative to standing which I found I tended to cheat a bit with other body parts.
One of my favorite ab exercises if there is no good equipment is grab a swiss ball. Put weight plates on your feet and do crunches holding dumbells behind your head.
