The Core muscles and the exercises associated with that area of the body have been a popular area of both discussion and activities over the past decade. It gained a lot of popularity with different types of videos and the popular MMA style of fighting. The reason why these muscles are so important, especially with these professionals fighters is because they are constantly being attacked from all different angles, and when it comes down to it, if they are do not have a great base, Core muscles & stabilization muscles, they are going to be off balance and succumb to losing their matches.
There is a lot more that goes into their training, which I am not an expert on, but when it comes to core, stabilization and balance training, I know for sure that it plays a vital role in how they train and when they compete.
When it comes to the regular fitness enthusiast, making sure these muscles are extremely strong and agile will help not only in a closed fitness setting, but also in daily life with regular activities. When you want to train for real life movements, but in a closed setting, we call this functional training. If you are interested in this, then you should do some research and ask a fitness professional in you area.
