Here is Mark doing a simple movement to improve shoulder mobility (Shoulder Pass Throughs).
I can't over state the importance of a good warmup which includes simple mobility and corrective exercises within it. Doing a little each day will go along way for performance, recovery and injury prevention.
Each day we begin our workouts with various drills to correct and improve common movement pattern issues. More to come on what we do at CrossFit Spokane.
We have several programs to fit anyone.
