Yin is a slow, floor-based practice where poses are held for 3 to 5 minutes or longer. The target isn’t muscle, it’s the deeper connective tissue, the ligaments, fascia, and joints that more active practices don’t reach. The long holds create a mild, sustained stress on those tissues, which is where the benefit comes from. It’s not comfortable in the way a restorative class is. You’re not trying to relax into the pose so much as stay present with it. That’s also what makes it meditative. There’s nothing to do but breathe and wait it out. Good for flexibility and joint health, and a useful counterbalance to stronger physical practices.
