Japanese Clover Clamps

These 3½ X 1½ Japanese clover clamps have small, rubberized teeth that create a firm grip around the nipple. Get them with a connecting chain or just a ring at the end of each for attaching weights, ropes, or other objects. Practice makes perfect, so start slow and work your way toward longer and tighter training sessions. Don’t worry if he screams — that just means the training is working.
