If you want to lose weight 15kg, you can replace the sit-ups at noon with push-ups, because push-ups consume several times as much energy as sit-ups! But kicking for 30 minutes may be too long, which is not conducive to blood circulation in the legs. 15 minutes is enough. You don't have to eat less for three meals, but you can eat more vegetarian dishes and tell you a secret. If you only eat vegetarian food at noon, you won't feel sleepy all afternoon! If you do this for a month, 15 kg is not thin, and 10 kg is definitely thin!
