Look at all these "experts" arguing with each other. That's why you don't coach everything at once to someone who's in the early phases. A lot of it also has to be contextualised, there's not always a SPECIFIC way to step in on each jab and all that shit. It's good to have tools and options, various entries and such, but again, you don't overload someone with information like that. You're doing him a disservice and actually hindering his learning with your nonsense.
Also,
@Woldog and
@Lastofthemohican put up some videos and let us see your work. I'm not disputing you could be pretty good, whichever style you imploy, but it's empty bravado at this point. Even if you were good, a good fighter doesn't necessarily equal a good teacher.
@Ilk You just do you. Pick a few things and work on them. Despite what these clowns say, you are getting much better than you were months ago, it's evident by the footage compared to last. The "lazy" jab they were referring to is you pawing the bag in range, not returning to your face and standing there. That's a dangerous habit. Practice returning the jab to your guard, to the holster, so to say. That's where it belongs. Then down the road when you get that ingrained, then you can start playing a bit with pawing and hand trapping, or whichever.
Again, work seperately on your footwork (lateral) and a few pivots. This needs work. Imagine your opponent in front of you on the bag and keep your guard active. Return the jab to the holster and be prepared to block, and work on the hooks on their own many, many times. That's what I would work on right now, and that's more than enough. If it's too much, just focus on half of it to begin with. Quality training over quantity. You will get better if you do the work right, it's all about mastering the basics.
You understand how the hips are the basis for all headmovement and punching in boxing right?
Don't worry about the specifics in the stance, and it is a bit exaggerated here (it's okay to do that when you're practicing a punch in a vacuum), but do this for working on your hooks. Also, what he is doing with his hips is an essential part in both moving your head, and shifting your weight:
