Tam Lee instructs the following:
Yin/Deep Stretch Yoga
This Yin/Deep Stretch yoga class is a slower paced with poses or asanas held for longer periods of time—3 minutes to 10 minutes per pose is typical. This class is a complement for your regular practice. Yin yoga poses apply moderate stress to the connective tissues—the tendons, fascia, and ligaments—with the aim of increasing circulation in the joints and improving flexibility. There is little "dialogue" in this class, there may be music, it is room temperature, and please bring blocks and/or bolsters if you have them.
