Past photos of ATEEZ’s SAN, who mastered social media algorithms with the fancam (a video focused on one person) for the new song “BAD,” are becoming a hot topic. SAN has recently been drawing attention for his powerful physique on the stage of ATEEZ’s new song “BAD.” In particular, the part where he makes his chest muscles bounce in time with the beat has received explosive reactions through short-form videos, and his past appearance has also combined with that to draw attention. Unlike now, when wearing a tank top makes his arms and chest muscles stand out, at the time of his debut in 2018 he was a slim boy with long, thin limbs and an innocent face. Among fans, he is always mentioned as “the member with the biggest gap between the early debut period and the present.” In fact, SAN in the early debut period was the lightest in weight among ATEEZ members, and it is known that he himself regarded his thin body type as a complex. However, he overcame that complex through several years of exercise. Exercise, which he started from the desire to show a better dance line and performance, eventually became part of his daily life, and through continuous weight training he steadily built muscle in his shoulders, chest, and lower body as well. Recently, he has said that he places importance on continuing to exercise even for 30 minutes a day, and that he is intensively doing lower-body training for dancing, so body management is still continuing now. When he appeared on Kim Jong-kook’s YouTube channel “GYM JONG KOOK,” he also had his exercise form and understanding recognized, fully showing off his credentials as an “idol who has seriously worked out.” What changed through exercise was not only his body build. His stronger body, combined with his uniquely powerful dance lines, raised SAN’s presence on stage even further. When he wears a suit, he transforms into a cold and intimidating man; when he wears a tank top, he transforms into a wild and feral man. The body he built to overcome his complex has, before he knew it, become the most powerful weapon that completes SAN’s character. Fans’ reactions to his 180-degree-changed past and present appearance are also enthusiastic. They responded with comments such as, “Because he is the effort type, he seems even cooler,” “He was a kitten, but he has become a jaguar,” “Isn’t he a completely different person now?,” “Is he really the same person!?,” “I loved him back then too,” “I can’t believe he wasn’t naturally like this, but was an amazing effort type,” and “SAN is the best!” ・ATEEZ’s SAN, people are falling for his charm!
