Bid Khun

Bid Khun (also written as บิดขี้เกียจ) is a Thai term referring to a specific type of stretch performed usually upon waking up or after prolonged inactivity. It translates roughly to "lazy twist" or "lazy stretch" in English. The stretch typically involves arching the back, extending the arms overhead, and often a gentle twisting motion of the torso. It is commonly performed to relieve muscle stiffness and improve circulation. While often done instinctively, Bid Khun is also promoted in some traditional Thai health practices. The movement is considered beneficial for increasing flexibility and reducing fatigue. It is a simple, accessible exercise that requires no equipment and can be performed virtually anywhere.
