The DJ took to Instagram on Monday to share a new shirtless shot for his fans. In the candid snap, Harris makes a funny face for the camera as he shows off his impressive six-pack abs and big biceps.
So what's the "Feels So Close" musician's secret?
"On tour but also training for next Armani shoot! Staying in a gym routine while on the road is tricky, but as long as you don't drink, eat well, sleep enough and take one of those mad little ab rollers with u everywhere you'll be good," he posted with the sexy snap.
We're guessing it takes a tad more than eating healthy and sleep to look like that, but clearly the 31-year-old is doing something right.
The pop star first made headlines in December for his fit physique, when he shared a sneak peek from his campaign with Emporio Armani.
