Rethinking Biomechanics: Weight Shift Explained
This PDF presents a clear, reference-based explanation of movement within the Dyad system. It defines weight, weight shift, resistance, input, output, rotation, and translation using a single, consistent cause-and-effect framework centered on the greater trochanter.
Rather than relying on posture, force production, or muscle-based explanations, this document shows how movement quality is determined by weight position, lever resistance, and timing. Key concepts are reinforced through simple analogies—such as the sledgehammer—to make abstract mechanics concrete and usable.
This resource is designed for coaches, clinicians, and practitioners who want a precise, internally consistent model of movement that explains why certain cues work, not just what to do.
