ABSTRACT:
A sports training and practice device that comprises a trampoline having a resilient surface forming a playing surface, an arm extending from the trampoline, and a ball-like bag resiliently mounted to the outer end of the arm. The inner end of the arm has a collar for installation over one of the legs of the trampoline, and permits relative sliding and rotational motion therebetween. The collar and arm are slid and rotated on the leg until the bag is at the desired height and distance relative to the playing surface, and the collar is engaged to the leg at that point by tightening a bolt threaded through the collar to impinge on the leg. The bag and arm may be separately provided for addition to existing trampolines.
