Your legs are the strongest muscles in your body. Jiu jitsu systematically uses legs against arms wherever possible — guard retention, sweeps, chokes, and control all exploit this strength asymmetry. When your legs are engaged, you are using your strongest tools against the opponent's weakest.
Closed guard uses both legs to control the opponent's entire upper body. The guard player's legs overpower the passer's arms in any strength contest — this is why posture, not arm strength, is the key to breaking guard.
The triangle choke uses leg compression to attack the neck while the opponent defends with their arms. Even against a much stronger opponent, the leg squeeze overpowers any arm-based defence.
Spider guard uses the feet on the biceps to push and control both arms simultaneously. Your leg extension against their arm curl is an unwinnable strength battle for the passer.
The lasso wraps a leg around the opponent's arm from the outside, controlling the entire limb with hip and thigh strength. The arm is trapped in a leg-powered vice that no amount of curling can escape.
The body triangle compresses the torso using both legs in a figure-four lock. Core and arm strength cannot expand the rib cage against sustained leg compression — the strength disparity is absolute.
Ashi garami uses both legs to entangle one of the opponent's legs, controlling the hip and knee. The opponent must use their hands to fight your legs — a losing exchange of weaker limbs against stronger ones.
De La Riva hooks the outside leg around the opponent's lead leg while the other foot controls the hip. Both legs managing one leg and one hip gives the guard player a two-to-one limb advantage.
The gogoplata places the shin across the opponent's throat and pulls the head down with the hands. The choke force comes from the shin bone — a leg structure against the fragile throat — making it brutally effective when locked.
