How to use the upper-jab (long range uppercut straight from stance)

[AlexKid]

Do you use it like a powerful jab or set it up with the jab?

How do the pros use it?

Ive seen mayweather use it.

Its kinda simlar to teh straight lead, since it uses the hips and a vertical fist

Floyd uses it well as a counter-punch against southpaws. He will slip to his left, shoot it and then usually pivot out to the outside of his opponent. Watch this video and go to 11:00. Floyd talks about this exact punch.

Some people call it a up jab or a spear jab.

It's more of a setup.

Love throwing the left hook to the body after.
