Biomechanical Fitness Instructional Chart

Generate a monochrome grayscale technical illustration, a biomechanically accurate fitness guide with clear 3D anatomical diagrams, featuring scientific chart aesthetics, a minimalist style, and no artistic exaggeration. It uses a 2x4 grid layout (8 panels in total), with perfectly aligned cells, equal spacing, thin black borders, and numbered 1 to 8. The panels depict gender-neutral, anatomically proportioned figures, with consistent character designs across all panels.{argument name="training sequence" default="dumbbell training"} Sequence (Key Positions Only): 1.
