This is how manufacturers grip tennis racket in bulk & that’s our Functional Tennis Saber Training Aid The Saber is an on-court training aid that plays like a normal tennis racket but with a much smaller head size. This unique design with its 37 sq. inch head forces players to focus on ball tracking, optimise footwork, and execute a clean, efficient swing to connect with the ball. #tennis #tenniscoach #tenniscoaching
