The USA's Bethanie Mattek-Sands, the 2016 Olympic Games doubles gold medalist, teamed up with Tennis Warehouse to share some of her top tips on doubles skills and strategy.
"One thing I've noticed is that when a lot of players are at the net, they're watching the wrong opponent," she said.
She went through a special triangular drill aimed at increasing the number of shots a doubles player has at their disposal.
"The goal behind this drill is to mix up your shots in doubles," she explained.
And she also had some guidance for returning, specifically sending shots down the line on the second serve.
