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. The upper and lower limbs are tubular and contain separate upper and lower spring assemblies for applying tension to the bowstring through the cam mechanisms only when the bowstring is drawn from its initial preset position. The degree of initial compression of the springs in the upper and lower spring assemblies can be independently adjusted to adjust the magnitude of the forces exerted on the bowstring by the assemblies when the bowstring is drawn to thereby set the maximum drawing force for the bowstring and the relative forces exerted on the bowstring by the assemblies.
