The aim of this study was to find out the effect of regular aerobic exercise on changes in VO2 max within 20 meetings. This research is motivated by the fact that sport or physical exercise is very important to maintain and improve physical fitness. Exercise is divided into aerobic and anaerobic exercise. Almost all the energy needed for muscle activity is produced by aerobic and anaerobic processes. The effect of aerobic exercise is cardiorespiratory fitness, because exercise can increase oxygen uptake. One way to assess a person's fitness in carrying out activities is to measure VO2 max. VO2 max is the maximum amount of oxygen in milliliters, which can be used in one minute per kilogram of body weight. People who are in good shape have higher VO2 max values and can perform activities more vigorously than those who are not in good condition. Materials and Methods. This research uses a quasi-experimental method, a quantitative method while the design uses One Group Pretest-Posttest Design. In the research, the sample used was the PERTINA Boxing Team of Pekalongan City, totaling 10 people, with male gender, age 16.40 ± 1.17 years, weight 63.70 ± 5.21 kg and height 167.70 ± 1 .57 meters and a Body Mass Index of 18.99 ± 1.47. VO2 max was measured before doing aerobic exercise, and after doing regular aerobic exercise at the 6th and 6th meetings. Differences in results before and after regular aerobic exercise for 6 meetings were analyzed using the Excel Statistical Analysis Tool. Results. There was a very significant increase in VO2 max after doing programmed aerobic training for 20 meetings. Conclusion. Aerobic exercise for 6 meetings can increase the VO2 max value
