How to develop a strong jab?

[TacticalW]

Have your guard a little closer to yourself, fire off your left and make it corkscrew into its end position. Be lax, tense up for the last bit of your jab. Put your shoulder into it. Stepping forward with it also increases the power. Do it over and over and over again when training. Throw sets of 50s on the bag, singles, doubles, triples (or for as long as you can). Using light weights while doing proper technique is also a good way to maximize your snap. When your shoulder is more in the left-straightish position treat it more like a straight maintaining corkscrew and pivoting. Just don't keep yourself squared up.. I get a lot of compliments on my jabs snap and power and the fastest guys in my gym have trouble dealing with it.

mrboxer gave great advice.

i heard a story about a guy in my gym throwing 100 jabs every night before he went to bed with a kettlebell on his wrist. i don't know how good his jab was but he was a very hard puncher

Forgot to mention but another thing that made a noticable difference was the tricep dips. Do 3 sets of as many as you can do each time and "as fast as you can go" (completely extending and going down to a proper position). Do the day you work your tricep group and you'll get a decent speed/power boost for your straight punches. The difference was pretty noticable for me.

Try to improve your punching speed, punching_power = m*V*V / 2, m - mass, v - velocity.

P.S. must have punch speed measurement device

I'll assume you factored in the Cotto Coefficient.

Cotto as I know has very low mass, so his way is speed only.... true?

A stiff jab

There is more to a stiff jab than one might think. The single most important aspect of a stiff jab is stepping in with it. To start with, you should have your weight predominantly on your rear foot (right for orthodox fighters). Your legs should be relaxed and you should step in with your lead foot quickly. At the same time, your jab hand should be flicked out at maxium possible speed (to achieve this, you must be totally relaxed until the point of impact). Your jab should be straight, this means that your elbow should not go outwards creating a backhand effect, it should be straight to the target and the elbow should be kept close to the body. Just before impact, your hand should twist so knuckles are facing upwards and your hand which should be loose and open should suddenly tense and close into a fist. As a guidance with stepping in, your lead foot should land at roughly the same time ad your jab hits the target (when your arm is totally straight).

If I might direct you to Jack Dempsey's Championship Fighting, he devotes quite a bit to the "Stepping Left Jolt" or "******* Jab," as you put it.

imho, this is totally wrong method. My real speed measurement on my own personal computer using knockouter.com shows that if you want max speed in a jab - it must be like standard boxing puch, not a karate "tsuki".

You described the karate punch "tsuki". Karatists say that it's not the best fastest punch. Karatists look into boxing to improve their "tsuki".

You either misinterpreted what I meant or you are wrong. I used to backhand with my jab and noticed a significant power increase when using the method i spoke of. This is the method taught to me by my former world champion trainer Chris Pyatt who I have a sneaking su****ion knows more than Mr 3 posts!
