Three-person uchikomi (Three-person training)
The "Three-person uchikomi" (Three-person training) consists of a single contestant practicing a Waza against two opponents; one who is receiving the Waza, and a second who is assisting the receiver.
In this Three-person uchikomi (Three-person training) method, the third party stands behind the person receiving the Waza and holds his belt or his ankle, etc., to increase the load being applied to the "Tori" (Player executing technique). Tori (Player executing technique) must therefore use more force to execute the Waza, and, with repeated practice, learns to execute the Waza more powerfully.
Moreover, unlike in One-person uchikomi (One-person training), Tori (Player executing technique) actually engages an opponent in grips and submarining techniques, etc., acquiring a better feel for conditions in an actual contest.
