Abstract

An archery apparatus for optimizing the force exerted on the arrow upon release includes a frame or riser and a pair of resilient limbs extending in opposite directions therefrom. A bowstring is connected between the free ends of the limbs and includes a nocking point for engagement with the nock of an arrow. an arrow rest is carried by the frame and together with the nocking point on the bowstring define a shooting axis along with the arrow travels when departing the bow. A hand grip is mounted on each side of the frame adjacent the shooting axis for accommodating the left and right hands of an archer. A harness adapted to be worn by the archer includes a bowstring release mechanism for selectively holding and releasing the bowstring adjacent the nocking point. In operation, the archer after putting the harness on, (1) secures the bowstring to the bowstring release mechanism and flexes the bow limbs by forcing the frame away from his or her body with both arms, (2) aims the arrow toward a desired target and (3) actuates the bowstring release mechanism to propel the arrow toward the target.
