sometimes i notice that when i step with my jab unless my foot placment is spot on it feels like i cant get my weight behind the punch kind of like its out of alignment,I think it is usually when i have tried to take to big a step so am trying to comcentrate on taking little baby steps or someimes not even advancing at all still using the same motion as stepping but without actually moving forward if that makes sense.Also is it supposed to always be a straight step or should it be a little to the left as if widen the stance slightly?
