There's a couple games at our local Gameworks (they had a job fair there, I went, it was a total bust except for the 1hr free game cards they were handing out - I scored about 5, gave four of them to a friend who actually likes arcade games.) that are very similar to some of your descriptions. First off, there's Dance Dance Revolution - that game can actually get quite areobic at some of the higher skill levels. There were also some "pedal" games that featured a pedal-powered gyrocopter, the faster you pedaled, the faster you went on screen. Didn't try that one.
