Hello, exercise is certainly good for losing weight. Doing sit-ups every night is a good method, but it takes a long time to take effect. First of all, we need to stick to it, then gradually increase it from 50 to 100, and then stick to it for a long time. In addition, exercise such as running is also beneficial to weight control. However, you should pay more attention to your diet. Don't eat snacks, carbonated drinks, drink less, quit gluttony, eat less at dinner, and strive for five points full. If possible, we should insist on eating vegetables every day, eat less greasy food and eat more fruits.
