This episode features Dan exploring the molecular mechanics of stretching and explaining the biological effects that occur when we lengthen our tissues. Stretching receives a lot of incorrect information and poor representation on social media platforms where sensationalised messages overshadow true scientific knowledge. This episode establishes accurate knowledge by explaining human body structure and function using biomechanics beginning with molecular components and extending to larger systems.

Dan starts with an explanation of body organisation levels from molecular through systemic structures before examining how collagen, elastin and other proteins construct the extracellular matrix and provide connective tissue with strength and flexibility. The study of these molecules helps explain the behaviour of tissues during stretching and adaptation.

This episode confronts multiple enduring myths that self-proclaimed "instagurus" have circulated. The episode examines common myths by analysing claims which state "stretching kills tissues" and "stretching is only neural." Dan uses biomechanics and molecular biology principles to evaluate these statements while teaching listeners critical thinking skills for online information.

At the conclusion of this episode you’ll gain an improved understanding of stretching mechanisms at the cellular and molecular levels and the necessity of this knowledge for practical biomechanical applications.
