But don't worry, in fact, you are getting heavier, not fatter.
Weight and fat are not the same concept. If people who exercise regularly weigh the same as people who don't exercise regularly, then people who don't exercise must be fat, because the density of fat is not as high as that of muscles and bones, which leads to this result.
In addition, when you get fat, you should pay attention to proper diet control. But you can't eat or go on a diet. Eat less at most.
Exercise to lose weight is a long-term process. At first, there will be an effect of not paying attention to weight. With the increase of exercise time, it will gradually decrease, but you lose fat, fat, not weight. This is because you often exercise, and your fat is transformed into body muscles, but your body shape must have changed a lot.
