NYC Work Out/Accountability Partner?

Options
I'm looking for someone in the area with similar goals (you can see them in my profile) who wouldn't mind going to free NYC ShapeUp (http://www.nycgovparks.org/programs/recreation/shape-up-nyc) classes 3-4 times per week. Would also be cool if we could be accountability partners for the days we don't see each other and work out. I'm in need some serious offline support right now because I have no drive or motivation!
