As the weight I lift increases I'm finding that I'm noticing my core more. And I'm also noticing that it needs some attention. There's more to building a strong core than simply doing some sit-ups and crunches. Here is an example of what some of those muscles are responsible for and an exercise to target them:
RECTUS ABDOMINUS
- Location: Covers the area from sternum all the way down to the pelvis bone.
- Function: Pulls the upper torso to the hips
- Exercises: Crunch or Sit-up
OBLIQUE
- Location: Side of the waist.
- Internal Obliques
- Transverse Obliques
- External Obliques
- Function: Tilt and twist the torso
- Exercises: Side Bends and Decline Oblique Crunches
INTERCOSTALS
- Location: Between the side of the rib cage. It comes into play when you flex the torso and twist from side to side.
- Function: Elevation and depression of the ribs
- Exercise: Air Bike
SERRATUS
One of the interesting things about core exercises is that there are many of them that can be done with nothing more than your body and some room on the floor. They don't require a gym or any special equipment, just some time and dedication. Here's a list of 25 of them. The internet can provide plentiful examples of each one being performed.
There are two different types of muscles that make up the core: The muscles responsible for stabilizing respond best to isometric exercises held for a period of time or low-intensity (bodyweight) exercises for a higher number of repetitions. The muscles responsible for providing movement of the trunk respond best to increased loading (resistance) for a fewer number of repetitions—this rep range won’t make the muscles bigger, but will be more effective at stimulating the muscle fibers; for optimal results the muscles should fatigue before twelve repetitions. If you can complete more than 12 repetitions, increase the load or resistance of the exercise. When using heavier resistance for a fewer number of repetitions, the rest period between sets or between circuits should be longer. For example, an exercise with a heavy resistance for 6 repetitions should be followed by a rest interval of 1 ½ to 2 minutes.
For some reason I have resisted focusing on my core but I do believe it's time to change that. It is part of the strong foundation and a house built upon a poor foundation won't last long at all. And cardio, I loath cardio. And I need to do more of that too.
