Both programs have the exact same curriculum and staffing. The main difference is the pace of study. Some people prefer to learn while fully immersed in yoga, and others prefer to digest the information a little at a time, over the course of nine weekends in six months. Our 4-Week Immersion is an intense experience of living, breathing, sweating, and dreaming yoga! This dynamic program works well for those who like to focus on one thing at a time or whose schedule allows them to devote four full weeks to the study of yoga. There is time after the training is finished to complete homework assignments. Our 8-Weekend Program moves at slower pace, with time to absorb, assimilate, and bring insights from the classroom into your daily life between sessions, which is then followed by regrouping together during training weekends for problem solving, Q&A, and continuing our journey of yoga. This program works well for those who need to keep regularity in their daily working and family lives while going through the training program. All homework is due by the end of this program.
