Muscles ... you know, only when all the fat is consumed can you grow muscles. In addition, running has some effects, but the effect is generally not obvious when you exercise. If you want to stovepipe, you can always try to walk on tiptoe, especially when you go upstairs. In addition, you can stand with your back against the wall at night, straight, with your hands straight to the left and right, your palms facing the wall, then lift your legs 90 degrees and then put them down. You don't have to do it if you are tired a few times. If you persist in doing stovepipe for a few months, you can still stand straight.
