[svlug] Open Source gym program

[Ivan Sergio Borgonovo]

I'm looking for an Open Source gym program.
It has to be Open Source since I would like to learn from the code (C 
would be better...).
I'm looking for something that will suggest how many minutes you 
should pass on a cyclette or step and other gym machines considering 
your fat %, height etc...

I've tryed on Freshmeat and Sourceforge, but I haven't been able to 
find anything. Maybe it's just a problem of vocabulary...

Any advice?

TIA
