Understand

You must never resort to force or brute strength. The moment you start to tense your muscles, your whole-body strength is gone.

A lower level student has difficulty coming to terms with the nature of whole-body strength.

The reason why you train it for years is so that you do not have to consciously apply strength when you need it. Whole-body strength is inherent; it is there all the time.

If something never comes or goes, why would you need to deliberately summon strength?

Until you understand this for yourself and have the faith that comes from pressure-testing your whole-body strength, you will remain a beginner.
