100 kilos

100 kilos is the BJJ-vocabulary name for a high-pressure variant of side control — the configuration in which the attacker commits maximum chest pressure across the bottom player’s torso, evoking the feeling of being crushed under “100 kilos” of weight.

Etymology. The “100 kilos” name is hyperbolic descriptive vocabulary — 100 kg is a memorable round number that captures the position’s defining feature of overwhelming chest pressure rather than reflecting the attacker’s actual body weight. The label entered BJJ vocabulary through Portuguese-language coaching contexts and spread to English no-gi through translated instructional material. The name predominates in pressure-focused instructional material; “side control” and “side mount” cover the position in broader vocabulary without the pressure-specific framing.

Mechanics. The position destabilises the bottom player’s escape options through committed chest pressure — the attacker’s full upper-body weight transfers through the chest connection into the bottom player’s torso, denying the bridge and hip-escape force that would otherwise be available with lighter pressure.

Cross-reference. “Side control” is the canonical position; “100 kilos” specifies the maximum-pressure variant of that position. Full mechanical coverage on Side Control.
