Working the core of the body has become a buzz word for just about every workout these days. Pilates focuses on the core, calling it the Power House. Functional training emphasizes core control for every day living. Sports specific programs emphasize the importance of rotation which occurs in the core. Where the disagreements occur are when deciding what muscles actually make up the core of the body.

The muscles associated with the midsection run along the trunk and torso and upon contraction they act to stabilize the back and pelvic area as well as the shoulder area. These muscles act together to generate incredible force and initiate basically all movement.

This article will focus on describing the muscles most commonly associated with the powerhouse:

The rectus abdominus is located along the front area of the abdominal wall and is the muscle that is associated with washboard or six pack look most people seek.  Crunches and reverse crunches are excellent for targeting the rectus abdominus.

The erector spinae is a group of muscles which runs along the back and is often associated with lower back strength or weakness. Back hyperextensions are an excellent way to target these three muscles. The multifidus is found below the erector spinae and runs along the spine. Its function and action is to allow rotation of the spine.

Internal and external obliques run along the sides of the abs and are worked by doing side crunches. The transverse abdominus is found deep within the abdominal area underneath the obliques. This grouping is responsible for protecting the spine and keeping you stable when your balance is challenged.

Hip flexors are also a part of the core and are located in the front of the thigh and pelvic region. Finally the gluteus maximus and medius are a part of the core as are the hamstring muscles. You work the glutes and hamstrings by performing squats and lunges. Not sure these exercises affect the core? The next time you initiate a lunge series or begin a squat workout place one hand (if it's safe) on your abdominals and see if you feel a tensing there just before the legs fire up.  You may be surprised at how connected the body is.  There is no doubt the core is critical to overall physical functioning and now you know the muscles that you need to focus on for a strong, well balanced mid section.
