In order to remain safe when exercising, and to not put undue pressure on our bodies, we have to have sufficient range of motion.
For this reason, mobility drills either to maintain or improve your mobility are necessary in your fitness endeavors. It is for the same reason that we have a specialty mobility class and insist on full range of motion during exercise. We give everyone tests that will help us establish exactly what range of motion we lack in what joints and then give you mobility and stability drills to help you improve. We follow the hierarchical order of mobility - stability - strength.
I participated in my first ever CrossFit Games, and trust me, it's a whole different experience. Out of the 48,846 women worldwide who did the scaled version of the workout, I was ranked 16; 942, and 372 out of 1,411 women in Africa. I am so proud of myself.
