Even if you don’t have a degree in anatomy or kinesiology, it doesn’t take a rocket scientist (or an exercise physiologist) to realize that very few injuries take place when you are lying on your back (unless you are an NFL player just lounging on his back on the football field and a 300-pound linebacker decides to swan dive onto you!).
This is why I never understood why the majority of core strengthening has historically been done lying face up on your back…eg all sorts of crunches. More recently, the plank has been introduced into the mix.
Most of us veteran instructors know that what goes forwards must also go backwards, so we’ve been doing back extensions as well as flexion (crunches) exercises for years.
As long as I’ve been teaching (almost 25 years,) I’ve emphasized the importance of “core” strengthening in a standing, moving, and twisting position as well as in a seated or lying position (side lying, supine or prone.)
If you have a strong core, as a result of doing functional exercises like the ones I teach in a FUNIQ class, your likelihood of getting injured when you are performing “life” tasks will be dramatically reduced!
Don’t get me wrong, we also do a variety of sitting and lying core strengthening exercises such as crunches and planks as well, which will really help improve your posture when you’re watching TV or driving your car.
