“A white male transforming from 150kg to 70kg over one year, facial features always consistent.
Begin with him overweight, training slowly in a gym, struggling on the treadmill.
Smoothly transition through the months as he lifts weights, sweats, and gradually becomes leaner.
Muscles start to appear clearly as his body fat drops.
End with him at 70kg, fit and defined, performing confident strength training in the same gym.
Natural, seamless body-shape transitions, realistic lighting, cinematic progression from obese to muscular.”
