Isotonic and isometric workouts can be used to avoid the buildup of fat in the belly, and young ladies should measure their waist circumference regularly.<br> <strong>Objectives. </strong>This study showed how isotonic and isometric exercise affected waist circumference measurements in overweight or obese young women.<br> <strong>Methods. </strong>This study adopted a quasi-experimental design. Participants were divided into two treatment groups, isotonic (n=34) and isometric (n=34) groups. The exercise treatment lasted three months, taking measurements at regular intervals.<br> <strong>Results. </strong>Both isometric and isotonic treatments reduced waist circumference by about the same amount.<br> <strong>Conclusion. </strong>Isotonic or isometric workouts can be done by young ladies as long as they are done regularly. Isotonic and isometric exercise, done three times a week for one hour, can help lower waist circumference, which will reduce the risk of central obesity.</div> Isotonic Training, Isometric Training, Waist Size, Central Obesity 0 0 http://aassjournal.com/browse.php?a_code=A-11-1902-1&slc_lang=en&sid=1 Surdiniaty Ugelta Surdiniaty@upi.edu 100319475328460010924 100319475328460010924 Yes Faculty of Sport and Health Education, Universitas Pendidikan Indonesia, Bandung, Indonesia Upik Rahmi upikrahmi@upi.edu 100319475328460010925 100319475328460010925 No Faculty of Sport and Health Education, Universitas Pendidikan Indonesia, Bandung, Indonesia Nina Sutresna nina.sutresna@upi.edu 100319475328460010926 100319475328460010926 No Faculty of Sport and Health Education, Universitas Pendidikan Indonesia, Bandung, Indonesia Pipit Pitriani pipitpitriani@upi.edu 100319475328460010927 100319475328460010927 No Faculty of Sport and Health Education, Universitas Pendidikan Indonesia, Bandung, Indonesia Asti Dewi Rahayu Fitrianingsih rahayufitria@upi.edu 100319475328460010928 100319475328460010928 No Faculty of Sport and Health Education, Universitas Pendidikan Indonesia, Bandung, Indonesia Ahmad Zaeri Sya'rani zaeri16@gmail.com 100319475328460010929 100319475328460010929 No Faculty of Sport and Health Education, Universitas Pendidikan Indonesia, Bandung, Indonesia
