I go to the little gym my apartment has, they have dumbbells. I will work out with dumbbells, even if people claim they are not as great. I can get a good work-out in with them.

I can still do compound movements with them, I can still train particular parts of my body, and I can train my body as a whole. I also add body weight training, I can't yet do squats with weight, push-ups, crunches, sit-ups, all those fun exercises. Dumbbells are just one of the many tools to help me get a good work-out in.
