A high-resolution, three-panel anatomical infographic composite image. Each panel is clearly separated by thin white lines. The style is that of professional clinical illustration and studio photography combined. Panel 1 (Left): "1. MUSCLES MOTEURS (PUISSANCE)". A front-three-quarter view of a male athlete performing a pull-up, mid-ascension. Studio lighting with glowing green overlay textures precisely highlights the active motor muscles: the LATISSIMUS DORSI (Grand Dorsal), TERES MAJOR (Grand Rond), and BICEPS BRACHII. Diagrammatic arrows indicate upward force. A text label reads: "LATISSIMUS DORSI", "TERES MAJOR", "BICEPS BRACHII". Panel 2 (Center): "2. MUSCLES STABILISATEURS (CONTRÔLE)". An anatomical close-up, posterior view of the upper back and shoulders. The athlete is nearly at the top of the pull-up bar. Glowing blue overlay textures highlight the active stabiliser muscles: the RHOMBOIDS, TRAPEZIUS (middle/lower), TERES MINOR, and POSTERIOR DELTOID. The movement muscles (Dorsals) are dark grey. Scapular movement diagrams are visible. A text label reads: "RHOMBOIDS", "TRAPEZIUS", "TERES MINOR", "POSTERIOR DELTOID". Panel 3 (Right): "3. MUSCLES DE GAINAGE (ISOMÉTRIE)". A full-body side-profile view of the athlete suspended from the bar, demonstrating rigid alignment. A vertical band of glowing orange overlay texture highlights the core/stability muscles: the RECTUS ABDOMINIS, OBLIQUES, LUMBARS, and GLUTEUS. A solid yellow vertical axis line shows the "rigid block" Mehr sehen
