If you want to run, it is suggested that you go jogging in the sports ground or the venue with running conditions from 4: 30 to 6: 00 in the afternoon if you have the conditions and time. It is best to keep running for more than 30 minutes, which is too short to achieve good results. After running, do a certain amount of leg stretching to move the ligament, otherwise the big legs will be strong and the stovepipe effect will not be achieved! If you can, you'd better stick to it every day. This will only be effective if it is maintained for a long time. Aerobic exercise will reduce body fat, so your stomach will gradually flatten out. If you are interested, you can do pull-ups, which is very helpful for waist exercise! It can also enhance the strength of upper limbs! I hope my answer can help you!
