Re: The "Jo Trick" and Similar Exercises

Thanks for all of the explanation guys. I can see where youre going with this, however, I still can't see how it can be done. If you extend your arm and extend a jo even further and someone pushes on the end of that jo, they are introducing a torque. The force at the end of the lever arm does not have to be great at all to generate a high torque at the center. If you are not going to move you have to generate a massive torque in the opposite direction (assuming youre using your legs/feet). How do you do that? Furthermore, if you have your arm extended how do you prevent that arm from giving out first. I mean a system is only as strong as its weakest link. I'd think that your extended arm would be that weakest link in the scenario where someone is applying a perpindicular force to it (with a mechanical advantage at that). Does anyone have any simple excersizes that I could try to experiment with this?
