I won't. Weigh yourself immediately after exercise, and what you lose is really water, because you will sweat a lot. But you said you had been holding on for two months. If it is a weight comparison under the same conditions, it is of course a real reduction.

As for your statement that the measurements have not changed, it may be because you have lost fat and gained muscle at the same time. Just stick to it. At the same time, as your body grows, the intensity of exercise should also increase synchronously, so as to achieve better results.

If you really want to lose weight in a short time, you must reduce fat with a low-calorie diet.
