Ahn Jae-hyun reveals intensive fitness routine for upcoming role

South Korean actor Ahn Jae-hyun has shared details of his intensive fitness transformation via his YouTube channel. To prepare for a bed scene in an upcoming project, the actor has adopted a rigorous seven-day-a-week workout regimen.

Ahn reported increasing his body weight from approximately 60kg to 77kg through consistent weight training, cardio, and dietary management. His routine includes performing 1,000 abdominal exercises daily to achieve defined musculature. He noted that his lifestyle has shifted significantly, moving away from previous habits like drinking beer to focus on protein intake and disciplined sleep patterns.

His physical goal is to achieve a balanced, well-defined physique similar to Brad Pitt in ‘Fight Club,’ rather than excessive bulk. His trainer noted that the current focus is on reducing body fat while maintaining muscular balance.
