Around 85% of us will miss a day of work at some point in our lives due to back pain. Much of this is because we go to work and sit in a chair for eight hours, sit in our cars to drive home, and then sit down to dinner. Over time this can reinforce poor posture which in many cases can lead to back pain.
At KP we NEVER do crunches and very rarely does anyone do any exercise in which the spine is flexed. Many people develop back problems from being in positions such as in the picture below.

Does that position look familiar? It’s the same posture used during a crunch or sit-up!

I have always suffered from bad posture throughout my years! It seems as though many young adults are quite adamant about exercising with crunches to work their abdominal muscles. Since this is clearly not a good idea, how would you instruct someone to work this muscle group?

Wow, i just read this and realized i was sitting the same way. And i never thought about how this resembled a crunch. Thanks for the incite into this. I hope i can change my posture to keep from getting back pain in the future,
Thanks again.
