I understand that if you throw a jab first, you use your rear foot to get the power. But do any of you use your front foot for the power instead to rotate the left shoulder more. If you do, 1-2-1-2, then on the second jab, you would use your front foot to power the jab. But the first jab was powered by the rear foot usually. I'm wondering in what instance do you guys use the front foot to power the jab instead of the rear foot. Using the rear foot helps you step-in, but I feel that I can get more power if I use the front foot sometimes. Of course, using the front foot limits mobility though. What are your thoughts on this? Hopefully what I said made sense
Use whatever works brother. I am assuming you mean pivoting the left foot to create more torque at the waist, generating more power. This would make your jab more of a straight left. Then again, you can literally throw the jab off the front foot (leaning forward, back foot in the air) ala Ali in his prime, peppering dudes all the while dancing around them. But I don't think this is what you were asking about.
Was kind of difficult to understand but i'll try to help. There are many jabs, light, lazy, sting, crack, stiff. Usually used this way: Light - Stiff Light - Sting - Straight Lazy - Crack Sting single Stiff single Sting - Stiff and many many more. A powerful jab can work at anytime but don't generally expect it to be a stunner. If you really want your jab to be a rock breaker then you can do what Cotto did, change stance. Cotto is a leftie but was trained as an orthodox so he could have massive jabs and bodyshots. Starting a combination with a stiff or stingy jab could be risky cause you usually lean a bit forward with it and are prone to counters. Spar alot and see what works.
If you really want a cracking jab throw it feet planted after you've stepped. Very hard to get down fluentlyy, when you do you will find countering counters off ur jab much easier. To get straight to the point, there are shots that you push into the target and there are shots that are pulled into the target, the latter is the better choice if u ask me.
You will see the front foot weighted Jab if a jabber just completed an outside pivot. For instance, Jab, step out slight pivot, Jab, step out slight pivot... Yes Some shots are front foot weighted and generate power from there because you are off to one side and its not biomechanically feasible to push off the rear leg. Instead you generate punch from a slight pivot and jink from the lead shoulder + foot. I tend to do this a lot as a southpaw. I believe the same mechanics apply to a lead hook (some people dont think so). A bow and arrow jab (as mentioned in an above post) is pushing off the front foot with a jab. So you are actually jabbing while transiting into a back step. You basically want the weight to be concentrated on the front foot to jab out and then push off backward.
There is a type of jab called jab from underneath or spear jab. It can be very power full, because you go down on your front foot and start the punch pushing with the front leg. Early Mike Tyson used this jab
Why are jabs thrown? To set up other punches. Not to knock someone out with. So why the infatuation with more power in the jab? And as with most things, there are trade offs. The more power you put into a punch, the more you commit yourself to getting hit. So the smart thing to do would be to get just enough power in the jab to do its job. Which is to set up combos and power punches. All the while retaining mobility and defense.
