Hey I was wondering if you all could give me a little advice on improving my left jab? I cant seem to get the power into it. I do JKD, and primarily your dominate hand is always leading, and your dominate hand is your jab and you use your other for your cross. But when I am boxing, my left would be up front. My right hand is my strongest jab and cross, but my right crosses are stronger than my jabs, so i would like to know how to improve my left jab, in a boxer's point of view. thanks.
