Visual perception changes as an actor's body composition evolves. During his tenure in early television dramas such as Veena and Haal-e-Dil, Mustafa possessed a significantly leaner build, weighing approximately 65 to 68 kg. That slender frame paired with loose, mid-2000s tailoring often gave him an elongated, sometimes fragile appearance on small-format CRTs.
Following his transition to commercial feature films in the mid-2010s, Mustafa undertook a rigorous physical regimen. By incorporating structured resistance training and functional conditioning, he increased his lean mass, bringing his working weight into the 75 to 78 kg (165, 172 lbs) window. Broadening his deltoids, expanding his upper back, and developing a firmer chest changed how garments sat on his shoulders. Tailored blazers and structured western jackets added horizontal presence. Rather than appearing purely tall and slender, his frame adopted a muscular, commanding density that translated onto silver screens in films like Quaid-e-Azam Zindabad.
