Is the best axis of rotation dead centre or the spine?

[frosty-g]

So ive found rotating the spine more powerful than rotating from the centre of my hips.

The spine isnt too far off centre but its a little further back.

Thing is the spine is linked solidly to the shoulders via mostly bone so it tranmits the force from your hip rotation to your shoulder rotation very effeciently.

Where as the middle of the hips links to your shoulders not via your spine but by the shell of your torso ie your abdominals obliques and lower back.

Which is the official and correct way?

What do you think of spinning the spine? Do you find it more powerful also?

(Please note do not twist the spine, but rather spin the spie using your hips, spin it from the hips you should feel no strain on the spine at all)

as well as spinning the spine try spinning your head, like in the film the exorcist. its what is also known as head movement

Interesting question.

What if we conceptualise the axis to the left shoulder when throwing a right hand?

If the axis is on the left shoulder the body would indeed swing like a door on a hinge and that would be a very very weak way to punch.

Its a very common analogy used by "boxing experts" but its a crap analogy, a boxing punch is more like a propeller, the axis is in the middle, both the left and right side have to spin, not just one side.

Which brings me back to my idea, since the spine is not central, that would mean there would be a very slight and subtle "door hinge effect" which is not good, but its only slightly off centre so its not that significant either, and the advantage is you are more directly connected to the shoulders with the spine spinning, and Im presuming the spine has less give than muscles of the midsection, so maybe it transmits force more efficiently, or maybe I need to work harder on my abdominals and obliques.

Just for the record, I don't teach the "Hinge" idea.

I was just throwing the idea in for sake of discussion. Regardless, an argument could probably be made in favour of this idea based on the distance from the axis to the shoulder. Physics show that as the distance from the axis increases (i.e. the lever arm), so does the force (torque). This could contribute to an explanation of why SOME tall, broad shouldered boxers have good straight right hands - i.e. broad shoulders = increased distance from axis to shoulder = more torque???

However, I know that punching power is extremely complex and I'm not aware of any concrete explanations using basic physical formulas. Regardless of what physics suggest regarding generating maximum power, a boxer has other considerations when in the ring.

Interesting topic. One that I have spent a considerable amount of time trying to understand several years ago - unfortunately, I don't have a degree in physics/biomechanics or the required depth of knowledge of these subjects (yet), so I'm just speculating.

However, I think you are on the wrong track regarding your ideas about how the spine connects to the shoulders etc - the function and structure of the spine / shoulder is the same and would transmit force the same regardless of how you conceptualise the axis of rotation. Assuming I am reading your posts correctly?

He's questions were so freaking annoying "best way to train and stay motivated? " bro go to a boxing gym and figure that out yourself -_-

As for this question, go to a gym and ask a trainer or some of the guys training.
