When we teach improper exercises, we start to use joints that are not part of the goal. We set the stage to de-emphasize this goal.
Why? Because if more joints are moving, what’s moving the joints? Muscles. What are muscles? Muscles are internal forces they’re helping out, and that’s important for you as a fitness professional to understand.
Your body’s job is to make life easy, when it experiences a stress or strain, it’s trying to dissipate it the best way it can. Remember the greater the difference between passive and active, the greater the risk involved.
This is a statement I want everyone to remember: “Just because you feel it, does not mean you are working it.” We had a dancer in one of our seminars who had excessive range of motion, and everyone said, “Oh that’s so great!” I said, No it is not great! We all have a certain amount of joint laxity.”
Here is a statement found on most certification tests: “The greater the mobility … the less stability.” That’s really important to remember when you start to analyze posture. You are going to find muscles that are short and facilitated, some that are tight, and need to be stretched or elongated properly. These postural distortions are going to disrupt smooth coordinated joint motion.
If a person has more laxity, we have to obey his or her body mechanics. The range of motion should be under the individual’s active control. Ask yourself “within what range of motion can you control the load”?
Step 1: Determine the engineering of the body (your body) is this the best exercise for me today?
Step 2: Can I control the load?
Step 3: At what range can I control this challenge, should I lessen the load?
Step 4: Go back to step one
