SHOW ME THE TEXTBOOK!!!!! Hahaha, you are so dumb that you don't realize that you are painting yourself into a corner. What Textbook exactly is stating the things you say?! Also, it would be some sports science or kinesiology book. And it's not there!! You are full of sh!t! Now I AM REALLY INTERESTED. @Test_Subject Do you know of this book?! See how the bullshit gets unfolded if you just ask questions?
