I don't know what you mean by doing a lot of exercise every day, but if you can guarantee 40 minutes of aerobic exercise four or five times a week. A month plus ten or twenty minutes of waist and abdomen training has no effect, then your diet must not be strictly controlled. Three points of hard work and seven points are in your own diet. As long as you can strictly control your diet, it will soon have an effect. Don't worry, take your time. The accumulation and consumption of fat is actually the reason why you consume less every day. If you want to be quick, rinse with white water, control oil and salt, and now add aerobic exercise, and you will lose weight in half a month, afraid of haha. However, it is better to take it step by step. I wish you an early success in slimming.
