I did some checking for you as well, and the closest thing I could find was a 1.5 hour drive to Pennsylvania. There was a University in NJ that used to do it was well, but they recently stopped.

There's also a mobile one in Boston, but again too far. Wish I had a better answer.
I know there has to be one, it's just a matter of finding it, the internet isn't always the best place to look, because the internet only shows the most popular sites that meet your criteria, not necessarily the best sites.
I think your best bet would be to call a few personal trainers and ask them, that would probably be your best bet.
