“A year-long body transformation of the same man, facial features consistent throughout.
Start in early spring, he is visibly overweight, jogging slowly in a park with soft morning light.
Transition to summer, sweating during outdoor training, boxing and lifting weights, his body slightly slimmer.
Move into autumn, running on leaf-covered trails, muscles becoming more defined, posture stronger.
End in winter, the man now lean and fit, doing a confident workout in crisp cold air.
Natural, seamless seasonal transitions, cinematic realism, showing the gradual journey from fat to fit.”
