The “core” is a common name given to the corsetlike muscles surrounding your midsection. These muscles are known as the powerhouse and provide a solid base upon which all other muscles can initiate movements in other parts of the body. When these muscles contract at the same time, they keep the spine in its most stable position. Keeping the abdomen and spine in their neutral positions will aid in preventing injuries and increase performance during daily activities, sports and work-related tasks.
