The Sit-Up and Your Spine

The Sit-Up and Your Spine

 

 

 

Here's a quick FYI!  The National Institute for Occupational Safety and Health set a limit for low back compression to 3300 Newtons.  This means that if you repetitively load your spine above this level, an injury is more likely to occur.  What's scary is that each repetition of the CRUNCH exercise produces this much force on your spine.  Some believe by bending the knees and performing the crunch, the compressive force is reduced.  According to a study by Dr. Stu McGill, this is not correct.  Dr. McGill recommends the Side Bridge Exercise for the abdominals and obliques.
