You are mainly aerobic now. Generally, there will be a plateau in the first month of exercise to reduce fat. During this period, the body's metabolic rate will increase significantly, but the fat will not decrease significantly. Fat consumption will be mobilized soon after the platform period. During this time, the water loss will be very fast, so you will feel thinner after exercise, and you will look thinner because your muscles are tighter.

Fat cells and muscle cells will not transform into each other, and it can be said that it is quite difficult for girls to develop into muscle groups because of physiological factors, and you can't do much without oxygen, but you must stretch after you finish.

According to your diet and training, I believe you will see the change of weight soon. If you persist, you will succeed.
