Davina McCall has become known for her washboard stomach and her inspirational exercise DVDs.
Now the ex-Big Brother presenter, 51, has stunned fans with another Instagram snap of her muscle-bound bod.
Pictured in shorts and a crop-top, Davina was smiling into the camera preparing for a workout.
She captioned the image: "Almost firing on all cylinders ... warm up walk run 20 mins then 30 mins @oygdavina revving up for back to school ..."
It wasn't long before her army of fans - one million of them - took to Instagram to share their delight.
Olympic gold medal winner Kelly Holmes said: "We need to run together."
Celeb pal Rochelle Humes said: "There she is," followed by a heart emoji.
"You are an inspiration for women over 50," a third follower wrote.
