An archery bow for a bow and arrow system comprises a main bow with a tensioner assembly designed to increase the pullback capacity and/or arrow firing strength of the bow. The tensioner assembly includes a first tensioner comprising an elongated bendable member made of a hard material. A middle section of the first tensioner is coupled to a main bow inner projection, wherein at least portions of the upper and lower sections of the first tensioner are offset from an inner side of the main bow, and wherein bending of the main bow causes the first tensioner to bend.
