Losing weight is a complex physiological process, which can reduce subcutaneous fat through aerobic exercise and form an intuitive sense of slimming, and at the same time it will be accompanied by a large loss of water in the body.

Legs are at 90 degrees to the body, legs are straight, muscles are tense, and balance is needed. Only by maintaining this state can subcutaneous fat exercise and be consumed to the extent you want. If only the legs are at 90 degrees to the body, but the center of gravity is leaning against the wall, the abdominal muscles of the legs are not tense and the body state is relaxed, it is impossible to consume fat to achieve slimming effect. In this respect, you can refer to some postures in yoga. The reason why you can keep fit is because the human body needs constant correction in the process of maintaining balance, and muscle tension is accompanied by the consumption of subcutaneous fat.
