A yoga block includes two opposite side surfaces, and a convex cambered surface, a plane surface. The yoga block allows users to achieve or maintain certain poses, stretches, exercises or therapeutic positions. Because of the bow-shaped cross-section, the center of gravity of the yoga block is lower than the center of gravity of the conventional rectangular or brick shaped yoga block. Therefore, the yoga block is more stable during operation when being located on the ground. Any risk of injury is reduced or eliminated due to the yoga block is toppled over during operation.【課題】安全性が高く、多様な形態で使用可能であり、多様な機能を有する、ヨガブロックを提供すること。【解決手段】平面部11と凸状の弧面部12とを連接して成る外面を有し、側面視で略半円形を成す。平面部11或いは弧面部12を床面に置き、足で踏んだり、背や腹部を載せて仰臥することにより、バランス感覚、柔軟性、身体各所の伸展訓練を行なう。弧面部12は、揺動時に可動支点となる。環境及び人体に無毒の材質から成ることが望ましい。【選択図】図1A
