Yoga blocks are supportive tools used in yoga practice to enhance stability and alignment. They are typically made from foam, cork, or wood and come in various sizes. By providing extra height or support, yoga blocks help practitioners achieve proper postures, making poses more accessible, especially for beginners or those with limited flexibility. Using yoga blocks can also deepen stretches and improve balance. They can be placed under hands, feet, or hips to assist in various poses, allowing for a safer and more comfortable experience. Overall, yoga blocks are valuable accessories for enhancing yoga practice and promoting better body awareness.
