Si. Some people actually do all sorts of exercises on there.
The claim is that since you have to stabilize yourself you recruit more muscle fibers, or something. I believe that muscles fire all or nothing.
If you want you can try some DB Bench Presses on them. They did nothing for me.....didn't help move my poundages up 10 pounds. The only thing that moves my poundages up is time off, then Progressive cycling.
