#2 This common error can easily be corrected by preferably placing the right thumb on top of the left thumb [or both thumbs right next to each other as a second choice]. You can now easily apply twice as much pressure to a single point [preferably on a nerve point] and make the technique much more effective with a lot less effort. There are many alternatives to using the right thumb: right hand, right forearm, etc.] However, whatever other part of your body that you’re also using to press against the tori’s hand, it should be pressing on your left thumb tip for maximum effect.
