What do they mean with “your core”?

Your core are muscles that keep you upright.

Think about it the only bone that connects our top half and lower half is our spine, which is in fact made up of many smaller bones called vertebrae and they are held together by ligaments, cartilage and muscle. Doesn’t sound like a very strong structure does it?

In order to keep us upright and our spine safe, we use our belly muscles and lower back muscles. These muscle are the ones we call “the core” and they make up a number muscle groups, but what you need to know is the areas that are important. The lower section of our belly leading into the pelvis (below waist line) is normally neglected the most causing a weak core and possible lower back pain.

There are many exercises that can enhance the muscles in the lower belly area. But a key tip is to try and push the muscles in that area inwards towards your spine as you do a sit up. Breath out as you go up and breath in as you relax and go back down.

I hope this explains a few things and makes more sense too.
