Bilateral Arm Control
Also known as Power Nelson — the canonical term used on this site.
Training background: Functional description
Functional — both-arm control from top position
Bilateral Arm Control is the functional name for the power-nelson — flagging the configuration’s defining feature: control of both arms simultaneously, removing the bottom player’s primary defensive limbs.
Etymology. “Bilateral” specifies that both arms are controlled (rather than just one); “arm control” attaches the controlling-category. The compound predominates in instructional contexts that emphasise the functional mechanic over the wrestling-specific “power-nelson” name.
Mechanics. With both arms trapped, the bottom player cannot frame, post, or contest grips — the attacker’s chest-and-hip connection is the only resource the bottom player has to address, but neither is reachable without arm participation.
Cross-reference. “Arm trap” is the alternate descriptive name; “power-nelson” is the wrestling-canonical label. Full mechanical coverage on Power Nelson.
