The hunky former Gladiator posted a picture of himself getting out of the shower this week in a bid to promote his new blog and wish his fans 'Good Morning'.
"Rise and shine!!!" he wrote beside the snap, in which he is seen flexing his muscles for the camera.
David, 27, is noticeably committed to working out and staying in shape, and now that he is rumoured to be dating 34-year-old Kelly, he has begun to train with her.
New couple Kelly and David have been enjoying themselves on holiday in sunny Miami, Florida and have now travelled to Los Angeles.
But they haven't used the break as an excuse to cut down on their exercise.
In fact, David and Kelly appear to be very committed to keeping fit in the States and have been hiking and juicing together.
The muscly fitness fanatic, who has adopted the nickname 'King David', uploaded a picture of himself and Kelly on one of their hikes earlier this week and wrote: "Day one of the McIntosh regime gym/hike/veg juice who knows what's in store for tomorrow."
Did he need to wear such tiny shorts?!
It hasn't been all work and no play for the smitten twosome though, as they've also taken time out to pose for some cute snaps on the beach and to play in the sea.
Over the weekend, Kelly flooded her Instagram page with selfies with David. We have to say, they do make a super cute couple!
