Adam Levine shows off his abs while training shirtless in Hawaii

Adam Levine may have moves like Jagger, but he pumps irons like Schwarzenegger.

The Maroon 5 lead singer shared one of the workouts he did while vacationing in Maui, Hawaii to stay in shape on his Instagram Stories Tuesday.

“They’re harder than they look,” he captioned a video in which he lifts a kettlebell weight while lungeing forward. “Shaky as fuq.”

The 42-year-old appeared in the clip shirtless, showing off his ripped and tattooed biceps and abs while wearing star-print shorts.

He was also seen with a freshly shaved head and a full beard.

Levine’s massive body made waves for the first time in late May when paparazzi saw him with his wife, model Behati Prinsloo and their daughters Dusty Rose, 4 and Gio Grace, 3 on a hike near a waterfall.

The singer of “She Will Be Loved” announced on social media that he has trained on the island with his longtime personal trainer Austin Pohlen.

In May, Pohlen published a video of Levine and Prinsloo, 33, who are doing step-ups together with the heading “Couples training”.

The fitness expert previously told Us Weekly that Levine was “very regulated” when it came to his exercise routine.

“He walks an hour and a half to two hours on the treadmill every day and then we train, but he also does yoga about three times a week and then just a little less, but yoga really helped him,” said Pohlen. “And then we do Pilates one day a week.”

He added, “We train strength four to five times a week. And [he’s] I’m just working on getting leaner and gaining muscle mass at the same time. “
