Calling all buff bods...

So, at the gym I now go to...because it's the only one...the weight room is extremely antiquated. I don't enjoy lifting by myself in the first place, but when I can't even tell if the contraptions they have are for my arms or my legs...I've pretty much determined I should just stay out of the weight room and stick to cardio.

That's where you all come in. I need ideas of things I can be doing to continue to work on toning my muscles up. Currently I'm pretty much just doing push-ups, squats, and lunges. There has got to be more I can do without having to go back into that room and look like a moron again.

Shoot me some ideas if ya have any. I do have some weights at home...I just get tired of doing the same things all the time.
