Uppercut Method pros\cons

[OZZ]

Kiddo is right about the uppercut from a tactical perspective. I also think it is best suited to inside, close fighting..WHAM!Power from the ground up..
I see amateur fights where people telegraph the uppercut so bad it becomes basically useless because even a slower fighter can get out of the way.
Close, inside fighting with your back against the ropes, best time to land an uppercut.

Razor Ruddock had a punch he was known for he called 'the smash' which was like a combination hook-uppercut. He destroyed Michael Dokes with that punch; but he almost always telegraphed it and was really only able to land it with full effect if he already had his opponent stunned first.

I loved using an uppercut as a counter to the jab.

If you're throwing with your hips on these uppercuts, it shouldnt matter if it's 90 degree or 45 degree, as long as your arm holds up on impact.

The kessler shot above is a lot more like a jab shot from a little lower body position. It's much harder to use your hips for an uppercut on the front hand, it tends to be a push off the hips instead. In close you can apply a lot more body rotation to the shot, but I usually only threw it as a counter to the jab (I'm lefty), so I'd either hit armpit or dead on the chin.

Training uppercuts on a heavy bag? Not a good idea, unless you have some weird bag that I've never heard of...

I've found this type of bag very useful in working on uppercuts:

Having said that, I've never really been good at throwing an uppercut to the chin, only as a shovel punch to the body or while holding the back of the head with the other hand. I've never been comfortable punching the head in an upward line, but I've done a lot more sparring with body shots only than with the head as a target as well.

For whatever it's worth, I was watching a Benny the Jet thing, and he said to have a 45 degree elbow bend in hooks and uppercuts.

Then there is the dirty boxing method, as demonstrated here, where you grab the back of the head. Also, Fedor seems to use the "jabbercut" quite often, as he fires from way outside a lot of the times in order to get you moving backward.
