I have strong punches but for some reason, my left arm is not as coodinated as my right arm and it taking me a long time to get it as stong as my right. Sometimes when I swing a jab with my left, my elbow would high extend, i quess, and it would hurt like a bitch. The pain would be located right on top of the elbow, below the tricp. So instead of fast punches, i have to throw rough strong ones so it wouldnt flex out. Anyway to correct this problem?
