Nick Jonas is ripped. King of the shirtless selfie, the 25-year-old "Jealous" singer showed off how he maintains his fit physique with a high-intensity battle rope workout. Nick was training with performance coach Matt Blank and said it was "another killer workout." Sounds like Matt knows how to keep Nick in great shape!
Although he was wearing a long-sleeved shirt, you can still see Nick's bulging biceps. With an intense game face on, it's clear that Nick was focussed on taking on the ropes; after all, using battle ropes is an excellent cardio and arm workout.
As Nick gears up to marry fiancée Priyanka Chopra, we're hoping he shares more sexy workout videos on Instagram. And if he wants to add to his collection of sexy selfies with a sweaty gym pic, we won't complain.
