People in their 80s are more often assumed to be housebound than hyperactive. But Sheila and Jake Stothard, 81 and 84 respectively, have recently found Instagram fame for their incredible fitness.

The Stothards, from Sunderland, became internet stars after their grandson, Phil Mackenzie, began sharing videos of the couple on his own page, Leansquad. The clips show off how easily the two can keep up with Phil, 37, who played professional rugby for London Welsh and the Sale Sharks until 2014; his “nanny” Sheila can be seen sprinting and leaping up stairs, while granddad Jake holds planks, lifts weights and finishes hundreds of push-ups in a row.
