Inclusion Criteria: * Currently employed as a full-time or part-time staff member at the hospital. * Aged between 18 and 65 years. * Voluntarily willing to participate in the 8-week dance program and complete all sequential phases (Phase A and Phase B). * Mentally and physically capable of performing moderate-to-high intensity structured exercise (such as solo Jive dancing). * Able to understand the study protocols and provide written informed consent. Exclusion Criteria: * Pre-existing severe musculoskeletal injuries, severe joint degeneration, or acute pain that restricts dancing or weight-shifting movements. * Uncontrolled cardiovascular diseases (e.g., severe hypertension, arrhythmia, or unstable angina) that render high-intensity aerobic exercise unsafe. * Current pregnancy or plans to become pregnant during the 8-week intervention period. * Undergoing regular professional or competitive athletic training that could introduce significant confounding effects to the physical outcomes. * Any other medical condition, severe cognitive impairment, or physical limitation judged by the investigator to pose a safety risk during exercise or interfere with data collection.
