Why Exercise?
Why are you exercising? One of the reasons I often hear is “I want to strengthen my core”. To do this many people are doing exercises (or thrashing about) while standing on an unstable surface such as a wobble board or a Bosu ball.
Another popular technique for developing a strong core is the plank. Now, I am a big fan of the plank since it demonstrates the principles of connection, linkage, tension, lengthening, etc. However, spending lots and lots of time practicing the plank will make you really good at doing the plank. This is particularly valuable if you fear that you might fall down in a dirty place with spiders and snakes on the floor and you will need to hold that position (about 8 inches above the ground) and be very still for an extended period of time.
A strong core that is only strong while you are stationary is pretty much useless. You need a core that can be strong while you are in motion. This requires two things:
- A core that is resistant to loading in a variety of directions, and
- The ability to use your arms and legs while your core is stabilized.
Enter the Turkish Getup.
Stability in Motion
This is a perfect example of a skill that requires a stabile core while the body is in motion. The weight overhead is supported and lifted by force directed into the ground. This force must go through limbs that are connected to a solid and strong core. The ability to maintain spinal length during movement is an essential element for most athletic activities. The muscles on our back put the spine into extension while the muscles on the front of the body put us into flexion. Both sets of muscles plus the muscles on the sides of our trunk must have a balanced amount of contraction in order to stabilize the spine in this straight, elongated position. You may consider this to be a good postural position and a corrective exercise for the many hours you spend hunched over your iPhone texting your friends.
Seated Position
The first move of the Turkish Getup involves moving from a supine (or lying) position to a seated position. If you tuck your chin and curl your spine into flexion as you perform this movement you will find that it pulls your arm forward, causes your leg to rise, and makes it very difficult to move into the seated position. Contract your abs while simultaneously opening your chest and lengthening from your head to your tailbone. This requires “core strength” in motion as you move from the lying position to the seated and nearly vertical spine position. The downward force of the kettlebell must travel through the arm, through the “core” and into the floor.
