One of the most recent things that I have been learning about is how significant thoracic mobility is when it comes to functional movements. Thoracic tightness causes a chain reaction of things to occur that can hugely compromise your performance.
Without going into detail, there are two main things that will tend to happen.
1) Increased load on the lower back due to excessive lumbar extension to make up for lack of thoracic extension in a Front Rack or Overhead position.
2) Increased load on the knees during squatting due to the hips needing to sit further forward to maintain balance.
Once correct mechanics are lost, one thing leads to another and you can find yourself with all sorts of niggles showing face.
Injuries aside, the other thing is that you will literally lack the range to hit the right positions and your true strength won’t be able to show itself. Don’t get caught in the trap of thinking you aren’t strong, you are, you’re just in a bad position. So instead of lifting heavier expecting to get better, take 10 minutes a day to work on your position and THEN your strength will show itself!
Below is a small video with some of the stuff I personally do to increase my thoracic mobility and stability!
