The key to losing weight is not going to the gym. The key to losing weight is to control diet reasonably and reject high-fat and high-sugar foods. You can definitely lose weight successfully. If you don't control your diet and just go to the gym, exercise will only increase your appetite and eat more. The more you exercise, the fatter you get. The most important thing to lose weight is to control diet. Exercise only plays an auxiliary role. The most effective aerobic exercise for burning fat is to use a treadmill. You adjust the speed of the treadmill to 6 kilometers per hour and jog for 30-45 minutes. At this time, your heart rate is about 120- 130 per minute. This is the most effective aerobic exercise to burn fat. Don't think that the faster you run, the more you lose weight. If you run too fast, your heart rate will be too high. You will only burn calories in your body, not fat. You can leave me a message if you don't understand.
