There are many great debates in life. As alluded to in the title, one of the greatest is what came first the chicken or the egg? In my opinion, when prepared right, they both taste great.
In Sports Performance, there is another similar question regarding mobility and stability. Some people say you need mobility first and others say you need stability first. Once again, I think both are great.
If you've followed our blog at HPI then you know that we've touched on both issues, but you also know we're big proponents of movement.
When it comes to training, movement is the umbrella that mobility and stability fall under. Basically, both are important, and both contribute to better movement.
I find when you train mobility in the presence of core stability both can be very effectively improved.
So before you start getting worried about what the athlete needs most ask yourself, "can they move well?"
I've seen very mobile athlete's that don't have the coordination to stabilize during a squat, or very stable athletes that don't have the mobility to get deep in a squat.
Ultimately; unless there truly is a need for mobility and stability, if you teach good movement the rest will fall into place.
