Team Europe celebrated Roger Federer's enthralling Laver Cup win over John Isner by doing push-ups.
The world No 2 came from a set down to defeat big-serving American Isner in a match tie-breaker following an entertaining battle in Chicago.
Federer's win left Europe 10-8 ahead with two more singles rubbers left to play.
But the men in blue celebrated the Swiss star's win in style by all getting down to do some serious push-ups.
Even 62-year-old team skipper Bjorn Borg joined in the party, along with Britain's very own Kyle Edmund.
