In wrestling, if you twist your opponent into one direction and he resists, you can borrow his resistence and twist him into the opposite direction and take him down. The ability to twist is very important. Today when I worked in the gym, I found the "rotary torso" machine that I can use for this purpose. Those 2 arms in this machine is just like 2 human arms. If you can twist it with 180 lb weight 30 times none stop, you should have no problem to twist a 180 lb guy down to the ground. You can develop your arm muscle, body function, and twisting ability all at once.

Next time when you go to your gym, will you give it a try?
