The Take That singer has launched his own bootcamp across Twitter, and is sharing his own fitness tips.
Gary has been helping fans out, sharing work outs and sending them encouraging messages.
The 46 year old revealed that he uses a food diary to make sure he keeps track of what he’s eating.
He wrote on Instagram: “A daily diary of food, drink and exercise is a great way of seeing where going wrong.
“I even log my water intake to make sure I’m getting enough. Being hydrated is a fabulous feeling. Most of us never know it. It also keeps the hunger pains away.”
Gary also shared that he relies on a ‘golden milk’ drink, containing almond milk and turmeric, to help him maintain his weight.

The dad of three has been open about his struggle with his weight, admitting he wouldn’t like to look how he did at his heaviest in 2002.
“My greatest fear is going back to where I was in 2002, when I didn’t have a record deal and I was very fat,” he previously said.
“I don’t want to use the F-word but I am going to have to, because I was.”
Gary said that he and his wife have overhauled their diets. “Dawn and I are pretty strict with our own eating,” he said.
He added: “I try not to be a food fascist around the kids.
“Dawn and I often eat separately from the children, as I frequently don’t get in until 7pm or 8pm, so unfortunately family meals aren’t quite like the ones I remember from childhood.”
