Understand the concept

If you want to know which one is more difficult to practice, the shark line or the mermaid line, you must first understand what they are. To put it simply, the shark line is the muscles on both sides of the abdominal muscles obliquely, that is, near the ribs. The scientific name of the muscle there is also called the serratus anterior muscle. Because it looks like a bullet clip, some people also call it the bullet muscle. The mermaid line is the muscle on both sides of the lower abdominal muscles, next to the thigh. If practiced well, the abdominal line will look perfect and attract people's attention.

Shark line

Generally speaking, the shark line is definitely more difficult to train, because the serratus anterior muscle is a small muscle group, and it is basically impossible to achieve the training effect in a short time through high-intensity weight-bearing training. Although the mermaid line is the same, but in that part, Men's body fat percentage is generally very small, so it is not very difficult to build a shape. However, the muscles above the ribs are actually very difficult to build. Unless they train specifically and maintain and recover scientifically, otherwise they will not be able to have a good shape. The effect is really difficult.

Exercise methods

Generally speaking, if you want to train the shark line and mermaid line, you can do abdominal crunches or abdominal abdominal exercises. If it is not possible, even doing sit-ups will have a certain effect. Anyway, as long as you can exercise the abdominal muscles, you can try it. Try it, but if you want better results, the Russian twist is better, especially the weight-bearing Russian twist. The training effect on the shark line and the mermaid line is amazing. The effect after long-term practice is quite good. of.
