Beast Hack is a patented modular baseball, softball and golf swing trainer equipment brand. Our modular baseball and softball hitting stations allow baseball and softball players to self correct their own swing using our patented angled rotating ball assemblies for instant feedback after each swing. Understanding the fifty-five degree of angle of rotation at which the ball rotates allows a hitter to understand their swing i.e. inside the ball, around the ball or behind the ball and how to correct it or improve upon their swing. In addition, this apparatus also let's the hitter understand at what point is there swing not under control (swinging too hard) promoting greater consistencies of making contact on the sweet spot of the barrel. The Beast Hack swing trainer can be used to train indoors, outdoors and even on the go with our standard 2" receiver hitch mount design. The Beast Hack swing trainer models are perfect for hitters of all ages and skill levels. There is no easier way for children to practice the art of learning to become a switch hitter as well. Travel ball teams, little league fields, personal trainer hitting instructors, professional coaches and parents will love the ease of setup, durability and price that the Beast Hack swing trainer delivers.
