Jab

[Scrap]

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.
