Running is the best way to reduce waist and abdomen. Personally, I don't need to run too hard, just jog. One hour after dinner every day, keep running 1 hour or so until you are sweating all over, and do sit-ups before going to bed. I have been running for a month, and the effect is obvious. I have also seen the people who run together make progress slowly. In addition, the diet is also properly controlled, mainly the intake of rice, eating more green vegetables and coarse grain fiber.
