At my gym job, they unveiled a new core class called CXWORX that I have attended on launch day. Basically this class uses a lot of resistance tube action along with some strange song choices to get your ab workout on.
Now I haven't done a lot of ab workouts since I strained my abs muscles back in February and the weight gainer has me kind of fat right now so this first time didn't go so well for me. Combine this with the fact that I have never done a group fitness class and you can pretty much envision me just trying to take in the atmosphere of this whole thing along with trying to do things right.
To be honest, I really enjoyed it and are planning on getting in there at least once a week for this class. My abs were sore in the good way for the first time in months. Will do again.
