Canada's Prime Minister Justin Trudeau has released a spoof Invictus video in reply to a challenge set by the Obamas to which the Queen and Harry responded in hilarious fashion.
In the politician's video he tells the US president, Harry and the Queen how Canada "brings it" and - with some of Canada's Invictus team behind him - does a press up before holding a one-arm press up.
Earlier Trudeau accompanied Prince Harry as he attended the launch ceremony in Toronto for the Invictus Games in Canada next year.
Harry told the audience of veterans, their families and military servicemen and women that "2017 will be your chance, your opportunity to salute those that serve your country; to salute those that put themselves in harm's way so you don't have to".
