I’m always cautious about the food I put in my body.” Hardcore strength training, however, can be risky for some type-1 diabetics, because it makes the body more sensitive to insulin and more susceptible to dramatic drops in blood glucose.“So we always keep glucose in the gym,” Miele says. And as for diet, we got his blood work done and put him on a specific blood-type diet to make sure he wasn’t eating any inflammatory foods that would hinder his goals or set us back.” Jonas trained harder than he ever had, and he relished the experience.“When I’m on the road,” he says, “I always make healthy choices.I don’t have a meal plan delivered to me, but I know what not to eat.He especially enjoyed the anonymity of a private gym, where, he says, he could be competitive with the only person who mattered: himself.“It’s important to stay in your lane,” Jonas says of his routine.
Meanwhile, Jonas the pop star is keeping plenty busy.
Miele looked at the calendar, saw that Jonas had three months till filming was set to begin, and got to work.
Miele’s goals for Jonas: reduce body fat, increase lean muscle mass, build power without compromising flexibility, and increase cardiovascular endurance.
In 2014 his eponymous solo album drew comparisons with another blue-eyed falsetto, Justin Timberlake, and his single “Jealous” leaped to No. And he can even pack arenas: When I meet him, he’s currently in the middle of a 42-date North American arena tour with his good friend Lovato.
To top it all off, when he isn’t impressing critics, he’s hobnobbing with all manner of royalty—music and otherwise—as when he was invited to President Obama’s birthday bash at the White House last August and got to pal around with Stevie Wonder and Paul Mc Cartney.
Simply put, Jonas needed to be “viciously strong, viciously powerful, and shredded,” Miele says.
