Bad posture?

its called the power line punch... When the distal radius and distal ulna don't overlap the wrist is stable. Jack Dempsey and Mike Tyson punched with thumb up. Refer to sugarboxing.com

 

If you look at the last split second nonito uses the torque from his hip pull to make forearm taut at POI.

Left hook is an abstract punch my man

 

Im sure ive seen tyson punching with his palm down ill look around for some footage but on the footage you supplied he does have his thumb up.
Dempsey certainly hooked with his palm down, heres a quote from his book. "Make your usual explosive landing with the second knuckle and with the fist palm down" this is taken from the chapter "hooking" pg 47 with picture illustration fig 31 and 32

 

"Wherever the hook starts or finishes depends where you direct the thumb thats the direction the elbow would take" wouldnt that just be the same for the whole hand?
Plus the knee and elbow should be in line sounds like good form.

 

I understand what donaire did in the clip but it still begs the question wouldnt it of been more technicaly correct with the elbow directly behind the fist?

 

Thumb is the main player from anything out of the 4th and 5th vertebrata, plus you would have trouble making a fist, without it. Also it orchestrates the elbow and shoulder.

Why don't you brehs bless us with some jewels instead of tellin us some stuff about some things.
If you say keep your elbows shoulders and hips in tune would you be helpin someone?
Or could you say punch like they are all attached by a chain? Hips shoulders then elbows with your knees bent! Where is your target spot? What happens to it when your body changes planes/levels? Does the target stay the same? If so how do you compensate for the extra energy to get to the same spot? Do you counter against the right hand, or with it?

 

Most important is to prevent injury a lunate fracture takes time to heal. S**** is correct about the H-recruitment wave in that it provides greater blood flow on the peripheral nerve. This occurs whilst the hand is in the prone position due to the stimulus pulse-width influences.

 

You're trying to over-complicate simple things. Your jewel is to think less and see how different movements feel. Boxing isn't an exact science and it's not that complicated.

 

What a load of chiropractic based nonsense. I really hope no one wastes time taking you seriously.

 

Its simple human Anatomy .

 

No it's not, you won't find that sort of nonsense anywhere apart from in the minds of chiropractors. It has no scientific basis and is a vague sort of statement that could be interpreted as anything.

 

Ive yet to meet, one of these chiropractors. But we would certainly be a different animal without the thumb, simple.

 

Very good post pal. Feeling the movement is so important.
