Take That fans get hot under the collar for Gary’s buff gym selfie... as they marvel at dramatic weight loss - MO

His total body transformation has taken some Patience in the gym.

But 45-year-old Gary Barlow was showing off the fruits of such steady dedication on Saturday, when he captured his enviable body in a gym selfie.

The Take That frontman wowed fans with his muscles flexed in a red vest top as he prepared for a yoga session.

Capturing the moment for fans to drool over on Twitter, the Never Forget hitmaker captioned it: ‘Gonna do a twitter diary today! First stop yoga’.

His camera skills immediately drew praise, excitement, and adoration from fans who flooded his Twitter feed with responses – with some so impressed by his physique they want to hire him to give them a workout.

‘I really need you to be my personal trainer,’ wrote one enthusiastic Take That fan, next to the picture.

Another fan echoed the sentiment and suggested the singer should open a branch of gyms, saying: ‘There needs to be a barlow boot camp! I’d join.’

Other fans were equally as mesmerised by Gary’s fitness selfie with reactions ranging from health concerns to requests for selfies with less clothes. 

‘Did you hear the noise? It was the ambulance taking me to hospital with a heart attack,’ wrote one impressed fan.
