Penelitian ini bertujuan untuk mengetahui pengaruh latihan angkat beban (weight training)terhadap penurunan lemak tubuh pada wanita dewasa di Gym Fitzone, Kota Medan. Metodepenelitian menggunakan pendekatan kuantitatif dengan desain eksperimen semu (quasiexperimental). Sampel berjumlah 20 wanita dewasa usia 25–35 tahun yang mengikuti programangkat beban selama 8 minggu. Instrumen pengukuran berupa body fat analyzer dan lembarobservasi intensitas latihan. Hasil penelitian menunjukkan adanya penurunan signifikan padapersentase lemak tubuh setelah mengikuti program (p < 0,05). Rata-rata penurunan mencapai 2,8%dari total body fat. Temuan ini menunjukkan bahwa latihan angkat beban secara terstruktur mampumemberikan kontribusi efektif terhadap pengurangan lemak tubuh pada wanita dewasa.References
