The original 240-hour program is a Hatha Yoga teacher training course, but many materials are included from different branches of Hatha. The same could be said for the basic 200-hour and 300-hour platinum courses. There are many different courses to choose from for teaching different groups, including prenatal and postnatal, restorative, vinyasa, chair, hot, kids, power and therapeutic programs. In each case, all of these are sub-styles of Hatha Yoga.
