Overview

According to Dr. Stuart McGill, professor of spine biomechanics at the University of Waterloo (Waterloo, ON, Canada), “The traditional sit-up imposes approximately 730 pounds of compression on the spine.” (McGill, 88)  This fact alone is enough to convince me to stay far away from crunches and all of its variations.

Unfortunately, Back extensions aren’t any better.  Back extensions on the Roman Chair (45 degree bench with feet anchored) creates 890lbs of compression on the spine (McGill 91).   In addition, floor exercises such as the “Superman” inflict over 1300lbs of spinal load and compression (McGill, 91).  I would have to imagine that trunk flexion and extension have doubled as a great client retention program for Chiropractors and Physical Therapists.

The primary function of the core is to stabilize the spine and maintain optimal alignment between the pelvis and the spine.  The core also helps to protect against excessive stress when the bodies extremities are in motion.  This makes no sense to me of why the majority of gym goers insist on adding hundreds of crunches to train our abdominals?  Well, it does make sense given the state of information in main stream magazines, infomercials and uneducated personal trainers.

Over the course of my video series I will provide alternatives to crunches and back extensions to build a strong and powerful core.  Please note that the video series is in no particular order.

*Please consult with a physician or any other health care professional before randomly trying any of these exercises on your own.  I will do my best to give progressions and things to be cautious about when necessary.

Part 6;  KNEELING SPLIT STANCE CABLE CHOP & LIFT

The Chop & Lift are great exercises for developing rotary strength safely and efficiently.  It is also a very effective exercise as the rotation of your lumbar spine stays well within the 0-13 degree range.  These exercises are a MUST for athlete’s and people who participate in sports such as golf, baseball, football etc, but are also just as important to the general public in keeping the spine healthy and happy which will help prevent against the “Shuffle” when aging.
