I doubt they were banned.  I just don't think they will come back.  Especially fat Courtney.  She was obviously uber-embarassed.  And there's tons of people in these classes, especially that one.  They have the guidelines for a reason!  This is the standard sculpt class.  Normally only 60 minutes but with 75 there's more time for flow yoga to warm up.  Its really tough yoga, and you can obviously go harder by increasing weight size, jumping higher, etc.  Not taking breaks.  Everybody takes breaks when they first start.
