You must lose excess fat first. Why can't you see the abdominal muscles? Because the fat covers the abdominal muscles, the outline of the abdominal muscles is not obvious enough. When you train six-pack abdominal muscles, your abdomen doesn't seem to have much fat at this time, but there is still some fat in the lower part of your abdomen, which blocks the key seventh and eighth abdominal muscles, so you should reduce fat and highlight the seventh and eighth abdominal muscles.
Moreover, it is difficult to exercise the seventh and eighth blocks in ordinary exercise, even if you lose fat, because those two abdominal muscles are too small to see. Therefore, you need to carry out targeted training, such as abdominal muscle wheel training, which can be carried out on the strength of abdominal muscles, but if you want to exercise eight-pack abdominal muscles, this is not enough.
You can do belly roll exercises. The key to belly rolling is that you can only train through the strength of your abdomen without the help of other parts. Do your best every time you train, so that you can exercise every muscle. When you feel that the strength is not high enough, you can also add some weight to your feet, and then do the back roll training. You don't need to do much training at a time, just 10, but you need to do more groups a day, so as to achieve the training effect.
If you want eight-pack ABS, you must control your diet and drink less beer. After you have meat in your abdomen, your muscles are not obvious. And don't pursue eight-pack abdominal muscles too much. Not everyone can build eight-pack ABS. Some people's genes determine that fat will accumulate in the lower abdomen and prevent the emergence of seven or eight abdominal muscles, but the remaining six can still be seen.
