Many martial artists believe that either jabs are useless or that back fists are useless.
This discussion is a basic approach to teaching how to make jabs as effective as back fists, or vice versa. You can begin from either a punching or a back fist perspective. Feel how you can lock it in the same way you lock your hammer fist. Work the angle of attack to the target and the shoulder line of the technique. Note how the maximum power connects when your shoulders line up with the target and the ridge hand strikes directly into the targert.
