Serena Williams is a beast who dominates women’s tennis. Recently, she won her 18th Grand Slam title at the U.S. Open. This made her the first female athlete to surpass $60 million from on-court earnings. Her on-court success is most certainly noteworthy, but so is her body. She is stunning and has an amazing physique. Serena teamed up with Beats by Dre to promote their new wireless headphones. The video showcases her body, work ethic and the preparation that goes into her training. Beat By Dre knocked it out the park because the ad is very inspiring.
