Shoulder Rehabilitation: 50 Evidence-Based Biomechanics Analyses is an open educational collection from the MMSx Authority Applied Biomechanics Lab (MMSx Authority Institute for Movement Mechanics & Biomechanics Research, Inc.). It contains 50 articles covering shoulder pain, rotator cuff tendinopathy, frozen shoulder, instability, overhead and pressing load. Each article pairs a biomechanical analysis of three movements (four 1080 × 1350 analysis slides) with verified research data, a three-step decision pathway (modify, load, track), cautions on when to seek assessment, and APA 7 references with DOIs. Biomechanics is treated as a mechanical decision science: force, direction, dose and tissue tolerance. Files: the full collection as one PDF; all 200 slides with the DOI on each slide; the website edition (HTML articles). Online edition: https://mmsxauthority.org/edu/analysis/shoulder/ The figures are educational estimates made from illustrated reference figures; they are not measurements of a patient and are not a diagnosis or a substitute for individual clinical assessment.

Instead, I build size with compound triads—deadlifts, barbell squats, and bench press—adding tempo bench for control and paused rows for upper‑back thickness.
