Sexercise

Bae Woong has always considered himself a formidable athlete, though his current physical condition tells a different story. Determined to reclaim the muscular physique he once proudly boasted about, he begins searching for a local gym to restart his training regimen. His search leads him to an unusually discreet and expensive fitness facility tucked away in the neighborhood. Intrigued by its exclusivity and having nothing to lose, he decides to step inside. However, the establishment operates under strict and peculiar rules. Before Woong can even learn the details of their specific workout programs, he is required to sign a legally binding nondisclosure agreement. While the secrecy initially strikes him as bizarre, the presence of exceptionally attractive female staff members quickly persuades him to comply with their unusual terms. Once the paperwork is finalized, Woong is finally introduced to the facility's closely guarded training methodology. He soon discovers that the extraordinary physiques maintained by the women working there are not the result of conventional weightlifting or cardio routines. Instead, the true secret behind their remarkable fitness—and the core of his new exercise program—is sex.
