The Yoga Triangle block is the most versatile yoga block available. The Yoga Triangle's patented gradient allows yogis to gradually deepen their stretch without the interruption of turning the block over. Unlike traditional yoga blocks that only have three heights (high, medium, and low) and one angle (90 degrees), the Yoga Triangle has hundreds of heights and angles (depending where you hold the block). The closer to the ground you hold the block, the deeper the stretch. The angles of the Yoga Triangle fit right where you need them to help you ease into difficult poses while increasing balance and flexibility. Yoga Triangles are made of high-density comfort-foam, which is durable, grippy, and lightweight. Finally a yoga block that makes yoga sense!
