How do you throw a jab?

Like reaching for something on a table and grabbing it.
From your defensive poistion extend your lead arm. You should wait till making contact before fully making a fist (grabbing from the table). You can step into the jab or chose not to. You should mix it up. You can also use the step to sell a faint.

make sure your chin is in the air

 

Yeah, if the girl in the video had any power in her striking she would break her wrist punching the bag like that + her stance is awful and the body is not behind the punch and head is up and shoulder isn't supporting arm when she hits the bag. The guy in the video is probably just trying to get some ***** with his video.

 

Not at all. It should snap out. You always have to twist the arm so that your elbow doesn't hyperextend. It's all one snapping motion.

 

as mentioned by some of the other posters earlier...there are several ways to throw a jab. u should master as many as possible. the thing to keep in mind is that a jab serves several purposes. it can be a range finder. it can score points. it can set up the bigger shots. it can actually hurt ur opponent. it can be ur offense and ur defense. ideally...u want it to be very snappy. i like bogotazo's comparison to a snake or a whip. u definitely want the jab to operate in that manner. i teach my guys to keep their palms inward (facing eachother) or forward (facing ur opponent)...this usually eliminates u lifting the elbow and creating the side to side motion (telegraphing) of ur arm that ur opponent can see so easily. u want it to be all about depth perception which is much harder for the human eye to read. keep the elbow in and let it drive the jab. when delivering the jab...u should be as relaxed as possible and the only time u are tense is in the fist at the point of impact. the jab should come back as quickly as it went out...and like the others have said...u want it to travel in a straight line returning to the point of origin.

as u throw the shot...u can turn it over to generate more power. u can step with it to bring more force. u can bend ur knee as u throw it. u can also put ur shoulder in to it. u should not be trying to throw the jab hard. it may seem counter-intuitive...but the punch will do more damage the more relaxed u are. trying to throw it hard is only going to telegraph it more. as u throw the jab...learn to position ur head in a manner where it will be difficult to get hit. some guys throw the jab with their heads up in the air asking to be ko'd. bury ur head into ur shoulder as u deliver the jab....or slide it slightly to the right to take it out of range. again....play with bending the knee as u throw it...stepping as u throw it...and make sure u bring the shoulder forward with the jab. a slight bend at the waist can also generate more power. i like to push off my back foot with my jab if i'm going to step with it or lean/bend my front knee. once u have mastered ur jab and can land it at will...step up to learning how to throw an "up jab."

side note...i like to land my jab or at least touch my opponent before i really turn in to it. i think of it as a range finder. once i've established range by punching at my opponent, i quickly switch to punching through my opponent by stepping with the jab and turning in to it. hope this helps.

 

Throw 200 jabs every morning when you wake up.
Its like brushing your teeth.
The most important punch in boxing.
If you cant hit your opponent with your jab, you probably wont hit him with anything else.
No jab. Pick another sport.

 

Imagine turning a tight fast crank. Turn over the hand at the point of contact, while stepping into it and always be moving your head. Keep the crank rolling back to return the fist to the defensive position or turn the crank again to snap out another jab.
