This place has great instructors though Paul himself can be quite inadvertently rude to the clientele.
I found that the class structure wasn't necessarily for me. I didn't feel particularly motivated to push through the session. I also felt like there was complete lack of focus on teaching any kind of technique. The style of the classes I attended was more along the lines of "hit the bag as fast as you can until you get tired. This type of workout may appeal more to those who simply want to break a sweat rather than those who want to see their physique and stamina improve.
We tried PBB on a Groupon and didn't even finish the package... Two stars for the kindness of the instructors.
