In Part I of this series I dissected a pig spine to demonstrate the risks of rotational movements like Russian Twists.  In Part II I talked more about crunches and why I think they’re a terrible exercise.

In light of all the controversy lately over Mike Boyle’s no squatting comment I thought it would be a shame if I didn’t include something on that subject as well.  Please watch and enjoy.

I should note that some people have commented previously that pigs do not stand upright so this doesn’t necessarily apply.  Unfortunately, when I asked my friends to use their spines them seemed unusually resistant to the idea.  The good news is that pig spines are a pretty decent model for human spines which is why many spine researchers actually use them in their research.

 As usual, please share your thoughts, comments, and questions below.

In Part I of this series I dissected a pig spine to demonstrate the effects of rotational movements like Russian Twists on the lumbar spine.  Today I’m going to continue on my quest to eliminate crunches from the mind of anyone who thinks they’re a valuable addition to core training.
