Resistance exercises for the upper body are relatively easy to adapt to home. Things like pushups and bicep and tricep curls with cans of whatever is in your cupboard (tricep curls: start with your elbows bent and poking out behind your back, forearms vertical, then extend your hands back and kinda upward - they should tone the "chicken wing" syndrome
). If you can get hold of one of those resistance bands (I think you can get them in sports shops) you can come up with lots too.
Also, see if you can beg or borrow a pilates book - I know mine has a few good upper body workouts.
If you have a suitable childrens park nearby, go do some chinups on the monkeybars, or do some gardening - whipper-snippering and wheelbarrow pushing and weed pulling would be good!
