Grip 'em Good
"Most of the match is in the grip," Selearis says. "Set yourself so you can attack his fingers." Grip as high up on his hand as you can, preferably at the base of his fingers. This will help you to loosen his grip and extend his arm away from his body, weakening his arm position.
"If you're wrestling right-handed, step your right leg forward—almost under the table," and plant it there. "Keep your hips close to the table, and all the muscles in your upper back tight." This position preps you to pull your opponent toward you and take him down.
If You're Going Down . . .
Should you find yourself nearly pinned, drive your shoulder toward your fist. "Try to push your shoulder behind it so your whole body is driving your shoulder forward." Your arm will follow.
