Diaphragm & Intercostal Muscle Stretches

The video tutorial explains the role of the diaphragm and intercostal muscles in breathing, likening them to Batman and Robin. It demonstrates three stretches to alleviate tightness in these muscles, each progressively more intense. The first stretch involves lying on the side, the second adds spine rotation, and the third uses a wall for support. Each stretch incorporates diaphragmatic breathing to enhance effectiveness.
