Some people have heard of bullet muscle, and some people have heard of shark thread. These are all popular words in the fitness industry recently, and they are also the latest standards for judging whether a person is in good shape or not. So what exactly are these two and what are the differences? For fitness beginners, they may still be confused. Let’s take a closer look at what is the difference between bullet muscles and shark lines.

What is bullet muscle

I believe many friends have seen bullet clips or bullet bags hanging on the body. This is why bullet muscles get their name. It is located on the outside of both sides of the ribs. If it is practiced well, it will look like two bullet bags hanging on the body, which looks particularly sexy and charming. However, this muscle is still relatively difficult to train. Some people are naturally very thin and tend to confuse ribs with bullet muscles, mistakenly thinking that they have bullet muscles, which actually makes a big joke.

What is shark line

Even if you have never seen an animal like a shark with your own eyes, you should have seen it more or less in movies and TV shows. So, what is a shark line? Like other fish, sharks have slits on the sides of their gills that look like a set of muscles on a human rib. If your figure is really good enough, when you raise your arms, there will be several muscle lines on both sides of the ribs on the outside. Generally speaking, the shark line refers to that place.

The difference between shark line and bullet muscle

From the previous explanation, I believe everyone has discovered that the bullet muscle and shark line are actually located on both sides of the ribs, on the outside. So what is the difference between them? In fact, there is no difference. They are the same set of muscles. It's like it's all the same movement. It's called push-ups in the Mainland, palm presses in Hong Kong and Macao, and push-ups in Taiwan, but they're just called differently. But it is true that this muscle is difficult to train. It is precisely because of this that people with bullet muscles are recognized by everyone as having a good figure and can be envied by everyone.
