Also known as: 戸川固め, まんぐり固め
A restraining pose where one person lies on their back with both legs raised toward their head in the Folded position, and the other person places their legs on top of those legs, pressing them down from the head side to hold them in place.
Not to be confused with Full Nelson, where the restrainer's arms are used to hold their opponent's legs. This involves the restrainer using their legs.
