Sorry, what i was saying and didnt explain, I got a terrible habit of assuming the obvious. The direction of the punch, The jab in this case, what moves most is the elbow. What directs it is the shoulder and back muscles. If they are not working as they should, it causes the elbow to lift, youre giving signals of intent. If the shoulders are working as they should this shouldnt happen,thats why i put those stretches up, it stops that happening
