Series 5.0 came in with Jeff's inspiration to teach and practice simultaneously, something he never did in larger group classes. This series is sweet and intimate. It is designed to be practiced sequentially, with each week of practice containing four classes total--three Green, 30, 45, and 60 minutes each, and one 60-minute Orange class. You will get excellent results if you pace yourself, listen carefully to the cues, and develop consistent practice.
