I don't know if you are a boy or a girl. If it is a boy, strengthen upper limb strength training. 20 kg dumbbell supine birds do 80- 100 push-ups every other day, divided into four groups, once 12-20. About the fatter lower limbs, you can play basketball to increase the bounce, which can well modify the lines of thighs and calves. Then there are sit-ups to increase waist muscles. There is no fat at the waist, and the proportion of upper body and lower body will be very harmonious. The latter two apply to both men and women. In addition to heredity (the probability is very small), this ratio is mostly due to lack of exercise, and the fat accumulation in the lower body and upper body will also become very thin due to lack of exercise.
