Thanks Pavel!

I never had any doubt as it has done nothing but make my kicks stronger and my press easier.

Due to the article, I could remind that if secondary mover activate before primal mover during any movements, the sheer force in our joint would be increased  and then can be created abnormal, painful stress.

Thanks for the sharing, Pavel.
