anatomical muscle model 3d

Create a full-body 3D male anatomical muscle model for a fitness app. The model should clearly show all major muscle groups with clean separation and readable anatomical forms, including: trapezius, sternocleidomastoid, deltoids, pectorals, serratus anterior, latissimus dorsi, biceps, triceps, forearm flexors and extensors, rectus abdominis, external obliques, erector spinae, gluteus, adductors, quadriceps, hamstrings, gastrocnemius, soleus, and tibialis anterior. Style: clean, educational, semi-realistic anatomical model, optimized for 3D app usage. Body proportions should be athletic, balanced, and natural, not overly exaggerated like a bodybuilder. Pose should be neutral A-pose, symmetrical, full body visible, arms slightly away from the torso, legs slightly apart, suitable for viewing all muscle groups clearly. The model should be front-and-back anatomically readable and suitable for rotation in 3D. Face design: simplified and low-detail. Do not make a realistic face. The fa
