When everyone talks about abdominal muscles, the first thing that comes to mind is the eight-pack abs, or the vest line or the mermaid line, but few people know about the shark line. In fact, this is because the shark line is very difficult to practice and it is difficult for ordinary people to have it. However, with the shark line, it can add a lot of points to our figure. Let’s take a look at the introduction of shark line freehand training at home.

1. Sit-ups

Sit-ups are a very effective way to exercise abdominal muscles. I believe everyone is familiar with this action, but please note that although sit-ups are simple, they only Only with long-term accumulation and persistence can you see obvious results. Generally speaking, doing sit-ups requires our coordination and speed. You may not be able to do it quickly at first, so you should practice it slowly. It is best to do 50 exercises a minute later, so that you can have the effect of exercising the shark line.

2. Cross-touch the ankles left and right

This action requires us to lie flat on the ground first, and then arch our legs to a 45-degree state. Then we bend our upper body. When doing this action, we need to ensure that our back is always off the ground, and then start to cross the ankles left and right. First use your left hand to touch the left ankle with force, and then switch to your right hand to touch the right ankle. In this way, the waist can clearly feel the forceful feeling, which means that our waist is already being exercised. Because the shark line is on both sides of our abdomen, this action can exercise the shark line very well.

3. Abdominal curls

Abdominal curls are also a very effective way for us to exercise abdominal muscles. The preparation for this action is similar to crossing the left and right ankles. At the beginning, we are all on both legs. Lie flat on the ground while arching, and then we start to do abdominal crunches. This action should also ensure that the back is always off the ground. When doing this action, we have to reach out hard, let our hands touch the knees, hold for 3 seconds, lean back and start the action again. A set of 30 movements, 3 sets a day.

People with shark lines are very self-controlled and can persevere for a long time. Because the shark line is located on the two sides of our abdomen, it is often easily overlooked and difficult to exercise. However, if we can practice the shark line, it can add a lot of points to our figure.
