Inside roll

Inside roll is the shorthand name for the inside arm roll — the bottom-position reversal in which the attacker over-hooks the near arm from turtle top, and the bottom player rotates toward the over-hooked side to convert the control attempt into a roll-through reversal.

Etymology. The “inside” descriptor renders the over-hooked-side direction of the roll: the bottom player rotates into the over-hook rather than away from it. “Roll” attaches the rotational-mechanic category. The shortened form is common in folkstyle wrestling and no-gi coaching vocabulary where the full “inside arm roll” is cumbersome; competition commentary frequently uses the shorter label. The naming follows the same pattern as “outside roll” (for the outside arm roll, the kimura-entry variant).

Mechanics. The roll uses the attacker’s over-hook as the rotational anchor — the bottom player rotates into the controlled side, using the connection the attacker established as the fulcrum around which the roll-through occurs. If the attacker maintains the grip, the rotation brings them over the top; if they release, the bottom player recovers guard without the over-hook danger.

Cross-reference. “Inside arm roll” is the full name; “outside roll” is the related kimura-entry variant. Full mechanical coverage on Rolls and Reversals.
