Joe Jonas is giving his brother Nick Jonas a run for his money in the muscle department!
The 27-year-old DNCE singer has been working out a lot lately, and letting fans track his progress via Instagram.
However, the former Disney star’s new physique was more prominent than ever when he was seen boxing shirtless in Beverly Hills this week.
According to TMZ, Jonas was working out with women’s boxing champ Ava Knight, and clearly taking his training very seriously.
Don’t get ‘Jealous’ Nick, but Joe might become the buffest Jo Bro yet!
