BL-56 - Support the Sinews
承筋 - Chéng jīn
Point Region: Shin
BL-56 Chengjin, meaning 'Sinew Support,' is a point that helps to relax the muscles and relieve calf pain. Located in the middle of the calf, it is a key point for releasing the tension that can accumulate from walking, running, or standing for long periods. This point provides a sense of 'support' for the muscles and tendons of the leg.
Think of Chengjin as a point that helps to melt away the tension in your calves. It's invaluable for addressing issues like muscle cramps, calf stiffness, and leg fatigue. By relaxing the muscles, it helps to restore a sense of ease and flexibility to the entire leg.
By relaxing the muscles and relieving calf pain, BL-56 helps to restore a sense of comfort and freedom in our movement. It's a point that reminds us that our ability to live fully is rooted in a supported and relaxed body.
