Weighted Training Ball

Abstract

A weighted training ball for use with a lacrosse stick assembly is provided comprising an inner ball core comprising an inner core density and having an inner core diameter. An outer ball shell surrounds the inner ball core and comprises an outer core density and having an outer shell thickness. The inner core density is greater than the outer core density such that said overall ball weight is approximately triple that of conventional lacrosse balls.
