Hitting the gym can be a daunting task, but one gran is absolutely smashing it by spending six hours a day working out.

Andrea Sunshine, the London-based fitness fanatic, isn’t shy about flaunting her toned bod or sharing her intense exercise routines with her massive 534,000 Instagram followers.

In her latest social media post, the buff influencer showed off her muscle-pumping shoulder workout using cables, followed by a cheeky jig in front of the lens.

The bombshell didn’t stop there as Andrea also blasted her triceps and back during the session. Her post was captioned: “Some serious upper body training.”

She added: “When you’re enjoying what you do, you forget the time. Up to 6 hours training unbelievable how is the resistance and the strength of our mind.

“The giant is back, and I am so proud of it! Good job!” The fitness guru rounded off her video with a timer snapshot, proving just how long she’d been at it.

Her post quickly racked up loads of likes and comments from admirers. One fan gushed: “Great job darling,” another crowned her “My queen.”

And a third praised: “It looks so intense but result is beyond perfection.” Just recently, the gran who turns on blokes half her age shared the secret to her hot body.

In her post, Andrea is seen bossing those ab crunches like a pro, then shaking things up by walloping the chest fly press machine.

Next, she switches gear to shoulder presses before torching her triceps on yet another machine. Not forgetting, she smashed through an ab workout.

But while she’s been training her major muscle groups, Andrea hasn’t forgotten to smile. She said: “There is nothing better than doing what makes you feel good and fulfilled as a person.”
