(1) thin belly: Drink a cup of warm water after washing your face in the morning, and then have breakfast instead of greasy food. After half an hour, jump rope 300 (you can lie down completely). Change your legs and jump (if you don't know, practice changing your legs before you start jumping). Do sit-ups without rest 120 times. Eat grapefruit in the afternoon (you don't have to eat it if you don't have it), and then steam some cauliflower (it takes 3 minutes). Do sit-ups before eating at night 100 times (you can't lie down completely, keep a little distance from the ground and then collect).

(2) thighs: running or doing actions that can warm up the whole body. Then switch legs and jump in place. When jumping, the thighs are parallel to the ground and the calves are vertical to the ground. Do it four times a day and jump 90 times each time (remember to jump once after changing legs)
