EXERCISES TO IMPROVE POSTURE

At the beginning of the seminar, I called for a volunteer to join me up front. I asked him to grab a dumbbell in his right hand and extend his arm straight forward from his shoulder and hold that position absolutely as long as he could. (You may recognize this test as an old military punishment, where a rifle is used instead of a dumbbell.) I told my volunteer that I would time his effort, but I would not give him any time feedback information until after he failed. He lasted 15 seconds. I then asked the man to repeat the test with the dumbbell in his left hand. This time, however, I informed him that he had lasted 15 seconds with the right arm and that I wanted him to try his best to beat that mark with the left. Also, this time I gave him constant time information feedback (that is, I counted the seconds elapsed). And as it happened, the other seminar attendees spontaneously shouted encouragement at my volunteer as he held the dumbbell aloft. This time he kept his arm raised for 22 seconds. My volunteer was right-handed. His left shoulder was no stronger than his right. “So,” I asked my audience, “how was he able to hold the dumbbell longer in his left hand?” The remainder of my presentation was essentially devoted to answering this question.d2wygncla0q7uxzpckht.png Allnewhairstyles
