do you find circuit training boring? there are lots of good quality classes at gyms out there. there's a class called 'bodypump' which uses a barbell, but it also has an aerobic component and the classes usually have about 30% male participants... boxercise and things like that are also quite good.
traditional circuit training can also be useful, or do your own circuit as part of a run a couple of times a week. this could include pressups, wall pressups, tricep dips, chin ups etc... if you pass through a park early morning the kids playground monkey bars can be of use...
all i used to do was 20x bicep curls and 20x tricep dips every evening, with 20 sit ups and pressups in a morning before joining a gym and it left my upper body in proportion to my lower body... i know that's boring but just think of it like cleaning your teeth...
