A group of 18 young men tried to fool a police officer into thinking they were doing a mass exercise class after breaching lockdown rules to meet up.
One of the youths filmed the incident on Saturday afternoon outside Birmingham's Lifestyle Express supermarket, with the PC seeing the funny side as he moved into the the middle of the group.
As he approached, a man ordered the others to perform high knees and then jumping jacks, shouting "let's go" with the others following his lead.
The cameraman tells the officer: "We're exercising, sir." The video was uploaded to Twitter on May 16 by event manager @iKhristenCraft with the caption: "Getting the 30 minutes of exercise with the community." It has since amassed more than 17,100 retweets and
