1. An aquatic exercise system for applying a resistive force to an exercising swimmer, for extending such resistive force to a number of swimmers, and for varying the number of swimmers to experience such resistive force, the applying and the extending and the varying being done in a safe, convenient, and economic manner, the system comprising, in combination:
a housing assembly formed of a plurality of hollow pipes, the hollow pipes being fabricated of polyvinyl chloride, the housing assembly including a base section horizontally disposed in a rectangular configuration, the housing assembly including a support section vertically disposed in a rectangular configuration with a top pipe, the housing assembly including an intermediate section angularly disposed and coupling the base section and an intermediate region of the support section, a water inlet port adjacent to the intermediate section of the housing assembly to provide water below the inlet port as a weight to stabilize the housing assembly, a water outlet port with a removable cover to facilitate emptying the water from the housing assembly when not in use; an operational assembly formed of four block and tackle subassemblies, each block and tackle subassembly including a fixed block with a plurality of upper pulleys coupled to the top pipe and rotatable around a common upper axis, each block and tackle subassembly including a movable tackle with a plurality of lower pulleys rotatable around a common lower axis, each block and tackle subassembly including a cord with a fixed end and a movable end and an intermediate section, the fixed end attached to an associated block, the intermediate section of the cord winding back and forth between the lower pulleys and the upper pulleys whereby pulling the movable end of any cord will raise its associated tackle; and a belt with a clip attached to the movable end of each cord, the belt configured to be positionable around a waist of the exercising swimmer during use while swimming for exercise, a water bucket attached to and coupled to each block and tackle subassembly for providing an increased resistive force to the exercising swimmer during use, a fixed eyelet attached to a pool during use with the cord passing through the fixed eyelet for guiding purposes, a movable eyelet attached to each water bucket during use with the cord passing through the movable eyelet for guiding purposes; the plurality of hollow pipes including two vertical end pipes, and a vertical center pipe, equally spaced between the two vertical end pipes, two block and tackle subassemblies of the four block and tackle subassemblies being located on each side of the vertical center pipe, the plurality of hollow pipes on one side of the vertical central pipe adapted to be removed along with the respective two block and tackle subassemblies to render the system for use by two swimmers rather than for use by more swimmers. |
