BACKGROUND
Technical Field
The present disclosure relates to a fitness-training device. More particularly, the present disclosure relates to a multifunctional core training device capable of changing exercise modes for core training.
Description of Related Art
Core muscles are located in the center of the human trunk and are for protecting the spine. The core muscles surround the waist, the abdomen, and the trunk center to the pelvic floor and are composed of deep muscles and superficial muscles in different parts of the body. During exercise, the core muscles contract before taking an action to stabilize the body axis, so that an injury caused by the lumbar spine displacement during the action is prevented. Therefore, the strength of the core muscles is very important for the human health and the physical flexibility.
To increase the strength of the core muscles, many different types of fitness devices for training the waist and the abdomen have been launched to markets, and a user can perform a strength training for different muscles. Thus, the aforementioned fitness devices become very popular. However, the conventional fitness devices have only one exercise mode, and the user needs to prepare extra-devices for performing a variety of exercising. Accordingly, the cost spent on fitness will be raised, and it requires more space for simultaneously using different fitness devices.
In order to solve such the aforementioned problems, a fitness device with multi-function is provided on the market. However, the fitness device with multi-function is heavier, and more space must be occupied when using different fitness modes. Thus, such the fitness device is not as convenient as predict.
Therefore, how to provide a fitness device that is easy to use and has different exercise modes for core training is a technical subject with commercial value.
