Using the reduction of the string sigma model to the 1-d Neumann integrablemodel we reconstruct the closed string solution with two equal spins in AdS_5which is specified by the number of round arcs and one winding number. From thestring sigma model itself as well as its reducion to the Neumann-Rosochatiussystem we construct a spiky string solution with two unequal spins in AdS_5whose ratio is fixed and derive its energy-spin relation. The stringconfiguration is characterized by the number of spikes and two equal windingnumbers associated with the two rotating angular directions.
