The soon-to-be 55-year-old took to her Instagram Stories to share the photo, displaying her ripped abs.
She protected her dignity by using some strategically placed emojis to cover intimate regions.
In a previous post, Meg showed herself working out with her personal trainer.
She captioned the post: “Fitness….. Turning 55 in a few 12 days and it’s only a number but muscle mass is so important my glutes and quads I work the hardest…
“Watch this space, two months strip back and building muscle. The last year Richie Swan has saved my mind and fitness, without him I don’t know where I would be today and start March 8… when the gyms and classes are open.
“”Do what you enjoy, mix it up..
