The “core” actually consists of many different muscles that stabilize the spine and pelvis and run the entire length of the torso.
When we are talking about core strength we are really talking about spine stability, even more specifically low back or lumbar spine stability.
Studies have shown that without muscles, the spine will actually buckle and cause an injury with only 20 lbs of weight. So how can some people manage to lift well over 10x that much? Well, the answer is muscles. And not only the big back muscles that you automatically think of, but also many small muscles found running in between each bone (called a vertebra) of the spine.
These “core” muscles stabilize the spine as we bend, twist, lift and extend throughout our lives. And it’s when these muscles are not doing their jobs properly that we run into problems such as injuries from lifting the heavy box out of the car.
Your chiropractor will provide you with a set of exercises to improve your core strength.
