Jiu-Jitsu (translated “art of gentleness”) emphasizes ground-fighting techniques and submission holds involving joint manipulations and chokes.
A larger more powerful opponent maintains the majority of his advantage in any situation where punches are exchanged due to his size and mass.
Using Brazilian Jiu-jitsu the practitioner puts himself in positions where only he can strike or nobody can strike. This can most easily and safely be done by bringing the fight to the ground.
BJJ advocates that a fight going to the ground is a high percentage occurance. If either fighter wants the fight to go to the ground, it likely will. Once the opponent is on the ground, arrays of techniques are used to maintain dominant positions and eventually move toward a submission.
Once the conflict is brought to the ground, positions that maintain striking advantage or ability to negate striking act as an anchor for an opponent. These positions give the Jiu-Jitsu player a platform to maneuver and attack from.
