8. Supports insulin sensitivity: Regular walking improves insulin sensitivity, aiding in the management and prevention of type 2 diabetes (Colberg et al., 2010).
9. Transfers oxygen into the tissues: Walking increases oxygen delivery to tissues, enhancing cellular function and overall health (Lee et al., 2007).
