I suggest you make the instrument first, but don't add too much weight.
After doing aerobics, I recommend you to do pilates, boxing, spinning, yoga and so on. These will exercise your abdomen. Only when doing these exercises, pay attention to keep your abdomen tight all the time, and the effect will be better.
In addition, we should do more abdominal exercises, such as sit-ups, hanging legs, rolling abdomen and so on.
Do it at least 20 times each time, divide it into 6 groups, and go to the gym to exercise different parts each time.
I don't think any exercise can minimize meat. Just to see what kind of sports you are suitable for or like. Actually, what I said above is more suitable for you! Of course, you can eat after fitness, but you should eat less and control the calories of food. You may like sweets at ordinary times, so it is good to eat less sweets in the future.
I hope my answer is helpful to you!
