Oh, cool -- it'll be fun for you to try "in person". The classes are an hour, oh, and by the way, I had other instructors than Burr, and they all had equally tough classes, but of course some have personalities you might click with better than others. But, I just wanted to make sure you know you don't need Burr herself, just going to the studio will be great, I would guess.
You start off by hanging all your weight on a bar for as long as you can. It's fun to see the time get longer the more times you do it. There's a bit of a warm up, some arm work with mini weights not at the bar -- don't try to go to heavy, believe me, those little movements can burn. Let's see, it's been a while -- I think at that point you go to the bar and do quite a bit of work. Oh, sometimes they would put in some stability ball work -- though it may have been slightly smaller. I can't remember. Toward the end of class you'd move to the floor for ab/core work. There's lots of stretching interspersed throughout the class and a nice long stretch at the end. No cardio.
When you go for the first time, they'll give you a good idea of what's going to happen and at least in SF, they were always very nice about helping the new people with positions and all. The class size could vary quite a bit -- when I first started going they were mostly not really big, unless Burr was teaching, but toward the end of when I went (about three years ago), it had really become popular and the classes were fairly crowded.
Have fun with it -- I think I made the mistake of doing too much bar method and not enough other stuff. As Cathe says, it's good to mix things up.

What can you expect from the your first class? Are there a lot of people? How long is the work out? Any cardio? Thanks Beth for your response.
