Jab

[RMorisseau09]

What is the best way to improve power on my jab?

[Sandman1995]

Ive only been boxing for about 7 months, after a few months i was trying to learn how to stiff jab
and he showed me how to do it and told me to hang a piece of paper from a string or anything, and punch it to where you can put a hole in it, it was pretty frustrating but i think it helped with me
im not a expert or anything, id have to see how you jab to give you some tips

Practice on heavy bag. It was created for this purpose

Technique is everything, dont smack the shit out of a heavy bag the bag is for technique, balance, economy of movement get it right or you'll damage your wrist shoulder etc. Think, practice and get it right, then accelerate it. Once you accelerate it dont even think about it anymore like a whip or drawing a sword or a six shooter speed equals power to an great extent once you are there and have the mechanics down.

Correct stance first.
Stand with the shoulder against a wall. Jab while moving the bodyweight.

Scrap taught me. You learn a lot about yourself.

Something I read on here that helped me 'pull dont push'

I am not sure how it is supposed to be executed, could you expand in a bit more details?

Ok, I'll try break it down.

1. Set up in your boxing stance. I'm assuming orthodox, left foot to the front, right foot to the rear.

2. Situate yourself next to a wall and place the left shoulder against the wall so that your vision is parallel to that of the wall. Vision not only identifies your target, it determines where you can attack, your ranges and your defence.

3. Your coach will have given direction to you as how he likes the jab thrown. For me, I generate force from the rear foot, pushing my weight forward through my glutes and core and slightly rotating my left hip as I extend the left arm. Many people speak of the left hip adding to their reach; for me the primary benefit is the left foot acting as an anchor so that I do not over commit.
The wall has dual benefits;
(i) will prevent the elbow flaring outward searching for speed.
(ii) will retain a vertical spine and good posture.

There are a lot more experienced and technically astute posters here. But thats my take.

It improves the Biomechanics of the Punch, also if the Muscles are not Flexible, you will Feel it straight away.

Thanks for posting those videos up scrap,I noticed the kid has his left heel raised and right foot flat,Is this to raise the left shoulder slightly so that the weight is slightly more on the back leg and head is slightly off centre?

Do you prefer the weight slightly more on the back foot as opposed to 50/50 distrubution? I tried it like this on the bag tonight and felt good,I imagine i would probably be harder to hit in this stance as it has more built in defence.

F=ma
Force is equal to Mass x Acceleration

Power = Weight x Speed (simple terms for boxing)

Without sacrificing the main role of the jab, you either need to gain weight or increase speed.

A jab is never going to KO someone so forget about power.

You want to improve your jab, improve your speed
You want to increase your power increase your speed

There is no secret formula, just jab fast, do not tense your muscles until impact, quit trying to get KO power with the jab, focus on speed, twice the speed hurts twice as much.

Do not try and telegraph a jab or get huge power from a jab.

Jab's effectiveness comes from its speed not its power.

Imagine taking 50 straight lefts/jabs at huge power.
Now Imagine getting hit quickly in succession with 50 lightning fast jabs.
Yes the later will hurt much more and stop you from countering.

Think less about power and more about speed, jab is not a KO punch, it is a range punch.

I prefer a little more weight, on the back foot. Thats your distance. Left foot slightly lift off the Heel, for turning the shoulder with the Foot, and if you need to push back, or spin. Plus the Heel being on the Floor when engaging, isnt good, its the Biomechanical break, it restricts, speed and movement. Sprinters do not run on there Heels.
