Why are classes grouped into sessions?
I found this is an important aspect to help prevent over-training injuries and prevent burnout in students and teacher alike. Having breaks imbetween classes allows for natural rest periods for any injuries to heal in. It also allows for the planning sessions which have improved the quaility and variety in the classes. And it allows for students to attend to other duties periodically that they can’t do so easily when classes are ongoing. By having breaks it also provides for mental relaxation and motivating to get back into classes when they start up again, thus preventing burnout.
