DJ/producer Calvin Harris is really taking his turn as an underwear model for Armani to heart. Not that we're complaining! The U.K. playboy is once again showing off his new ripped physique on Instagram, this time along with a bit of workout advice for travelers.
He writes: "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."
