Yoga Block FLOW Brick — A tool not just for beginners. The Yoga Block FLOW Brick is one of the classic yoga tools that should not be missing in any yogi equipment. It doesn't matter whether you are a beginner or have been practicing yoga for a long time, because the yoga block can also serve you well in advanced yoga practice. The yoga block is usually used to extend your arms; for example, when your hands do not reach the floor in standing positions. But you can also use the FLOW Brick to help you perform advanced asanas, deepen positions, or work on the correct orientation.
