This is one of the most effective tools we have found for teaching relaxed, diaphragmatic breathing. Watching the sphere’s three-dimensional action combined with the “belly breathing” activities in our book Yoga Calm for Children calms, centers and relaxes children and adults alike. Use it at the beginning of a class to focus the group’s energy and prepare for learning. Have a child use it when s/he is upset. Or use it when you need a break. It captivates kids by magically expanding from 5.5 to 12 inches and its calming action works wonders!
