What is passive traction in yin yoga?

Passive traction in Yin yoga refers to the effect on your body when you hold poses for a long period of time. When you flow through poses, much of the stretch that happens is in your muscles and tendons. But, in passive traction, it’s your connective tissues that are being lengthened as you practice. Proponents argue that this kind of stretching is key for overall health. They contend that it helps keep muscles and joints supple and frees the energy (Qi) in your body. Many poses in a Yin practice are held for several minutes at a time, so you can feel your body release tension even in simple poses.
