5 Types Of Crunches For Your Core


For perfect core undoubtedly, crunches are the best exercise. Your core comprises of your abs, oblique muscles on the side of your trunk, muscles in your pelvis, lower back and hip. These muscles play a very vital role in our body.

First and foremost, the abdominal muscles protect our organs from injury or shock. If you have your abdominal muscles flexed and someone punches you on your stomach, you will not get hurt because these muscles will act as a shield for your stomach. 

Secondly, all the muscles which contribute to forming a core provide stability and balance to your body. These are the muscles that help in defining your posture.

Crunches work on the specific regions of your abdominal muscles. There are many types of crunches and it takes a lot to decide which one is the right for you but trust us, there is one for everyone. So, to help you in this we have bought a fitness and mixed martial arts enthusiast Karthik to help you decide which crunch is for you. “Despite the popularity of the crunches, they are not suitable for everyone. For the people who have back relates issues and neck problems, you should avoid doing crunches because while doing these, your back and neck go through a lot of stress” say Karthik while talking about crunches.

In this article, along with Karthik, we will be talking about crunches and their types so that you can choose whether they are the right fit for you or not.
