Serena Williams will go down in history as the greatest woman’s tennis player of all time and in my humble opinion the best female athlete of all time. I still believe Federer is the greatest tennis player of all-time (men and woman.) One reason for Serena’s dominance on the court is her BIG, PENETRATING forehand. In this video I break down this amazing stroke and show how she is able to create power using her entire body in the process.
