Of all the TEN general physical skills: flexibility has the most potential to limit the other nine. Think about it. If you have limited joint range of motion, your ability to produce strength, speed, power, coordination, etc is limited. Conversely, if you have full range of motion, your ability to express your full potential in all the other nine skills becomes simply a matter of training.
1. cardiovascular/respiratory endurance
4. flexibility - The one that can limit them all. OR UNLEASH THEM!
So, regularly work on your mobility. I mean every day. Don’t be dysnormal.
