A compound spring-loaded archery bow, which retains the appearance of a traditional bow, has a rigid bow frame that is formed by a central riser with a handgrip and arrow rest, an upper limb extending upward from the central riser and a lower limb extending downward from the central riser. Cam mechanisms are mounted at the upper end of the upper limb and the lower end of the lower limb and a bowstring is secured to and extends between the upper and lower cam mechanisms. When the bowstring is drawn from an initial preset position to shoot an arrow, there is a synchronized actuation of the upper and lower cam mechanisms.
