#YouCantStopUs: Serena, Venus star in Nike campaign

Athletes are used to adversity, and players need to welcome it in order to succeed in their respective sports. Most days are far from perfect and tennis players know that there will be double faults and missed opportunities, but that doesn't stop them from pressing onward.

On Thursday, Nike released a social campaign using the hashtag #YouCantStopUs on Instagram.

"Nothing can stop what we can do together. You can’t stop sport. Because #YouCantStopUs," Nike wrote on Instagram.

The sportswear company posted a touching one-minute video on how athletes are never alone and how being held back and doubted doesn't cause them to crumble. Instead, it brings players and all sports together to go further than before.

The video shines light on not only the obstacles athletes face on the field or court, but also how they continue to break barriers off the court by standing for equality and fairness.

"We have a responsibility to make this world a better place," Lebron James and Megan Rapinoe say in the video.

Tennis' own Serena and Venus Williams, Rafael Nadal and Namoi Osaka make appearances in the inspiring video. The Nike clip reminds the world that although everyone is enduring a hard year, it's an opportunity to come out of it stronger than ever before.

"It doesn’t matter how far or how fast you run. Just by making it to the starting line, we make each other stronger," two-time Grand Slam champion Simona Halep wrote on Instagram.

Serena also posted a photo with her sister Venus. The two have jumped over both racial and gender inequality hurdles and have changed many things for the better even beyond tennis.

The sisters are a breathing testament to what athletes and the world can do when united.

The game's rising young stars like Andrey Rublev and Felix Auger-Aliassime took part, too.

"I consider myself very fortunate to be in a position to support causes that are close to my heart. In January, I launched #FAAPointsForChange in partnership with BNP Paribas, CareFrance and CareCanada," Auger-Aliassime wrote on Instagram.

In February, the world No. 20 started a campaign that helps educate children in Togo. With each point won by Auger-Aliassime, $5 is being donated to Educhange with BNP Paribas donating $15.

It's the many players like Serena and Venus, Halep, Nadal and Auger-Aliassime that are making the world a better place by not just letting their forehands do the talking but their voices as well.

"We know things won't always go our way, but we will find a way," Nike said.

The world is playing in its most important match yet, and although it's down on the scoreboard, it can't be defeated if united.
