The Rubber Guard is a grappling position used primarily in Brazilian Jiu-Jitsu and mixed martial arts. It involves the practitioner using their legs to control an opponent's posture while keeping them close. This position allows for various submissions and sweeps, making it a versatile tool for both defense and offense. To achieve the Rubber Guard, the practitioner typically places one leg over the opponent's shoulder and grips their own foot or ankle. This creates a strong control mechanism, limiting the opponent's movement and opening opportunities for attacks like the triangle choke or omoplata.
