Introduction: Adults aged 20–40 years often exhibit low awareness regarding the importance of maintaining health. Physical inactivity and poor dietary habits can negatively affect body composition, particularly body fat percentage. Both insufficient and excessive body fat can adversely impact health. Dumbbell resistance training has been proposed as an effective intervention to control subcutaneous fat, particularly in the upper arm. This study aimed to investigate the association between dumbbell resistance training and upper arm fat percentage in adult women aged 20–40 years in Denpasar, Indonesia. Methods: This cross-sectional analytical study employed purposive sampling to recruit 33 adult female participants who met the inclusion and exclusion criteria. Data on dumbbell resistance training duration were obtained through interviews, while upper arm fat percentage was measured using a skinfold caliper. Spearman’s rho correlation test was used to examine the relationship between training duration and upper arm fat percentage. Results: Analysis revealed a significant negative correlation between dumbbell resistance training and upper arm fat percentage (p=0.003, p<0.05), indicating that longer training duration was associated with lower fat percentage. Conclusion: Dumbbell resistance training is significantly associated with reduced upper arm fat percentage in adult women aged 20–40 years in Denpasar, Indonesia.
