What if the hamstrings aren’t simply “tight”… but misunderstood within a limited model?
Building on the foundation of our previous Big Toe / Hallux webinar, this session with Anatomy Trains senior teacher Michael Watson continues the exploration of how movement is organized from the ground up. If the hallux is where awareness and propulsion begin, what does that mean for the way we understand the hamstrings?
In this webinar, we move beyond the traditional posterior chain perspective and explore the hamstrings as part of a broader, more integrated system. Introducing the concept of the “4th hamstring” — the posterior fibers of adductor magnus — we begin to uncover its role in hip extension, medial stability, and its deeper relationship to the Deep Front Line.
From this lens, extension is not something that starts at the hip — but something that emerges from the ground. We’ll explore how triple extension is initiated in the foot, with the hallux and forefoot driving a coordinated wave through the ankle, knee, and hip. The hamstrings — and the “4th hamstring” — become responsive participants in this sequence, rather than isolated drivers of movement.
Rather than chasing length, we’ll re-examine how tension is organized, how control is expressed, and how these tissues participate in whole-body coordination. This offers a powerful shift in how we assess, cue, and work with the posterior body — from isolated structures to integrated function.
Designed for Structural Integration practitioners, manual therapists, and movement professionals, this session invites you to refine your lens, challenge familiar narratives, and deepen your clinical and perceptual understanding.
Students will have lifetime access to the recordings.
This course will be provided over Zoom webinar with live chat and Q&A.

Michael Watson’s journey of self-discovery has led him around the world, teaching and sharing his passion for anatomy and alternative modalities of exercise and therapy.
Beyond yoga, Pilates and Anatomy Trains teaching certifications, Michael leads advanced training programs, retreats and clinics worldwide. He has worked with athletes with disabilities at the Paralympic level of training and continues to develop ideas that bring an integrated approach to health, movement and wellness. As a certified teacher of Yoga, Pilates, functional anatomy and with a degree in Sports science, Michael brings an in depth awareness to his clients based on a strong understanding of anatomy, the body and its function.
A proud father of 3 home birthed children, Michael is also a natural birth advocate and works progressively in his home base of Bermuda alongside his wife in bringing awareness to birth and reforming birth options for women.
