Um, someone's been working out. A LOT.

Nick Jonas Instagrammed an out-of-character shot today. Usually the 20-year-old shies away from selfies and snaps his brothers performing.

Luckily for us, the youngest of the Jonai turned the camera phone on himself and showed us his impressive physique.

You know, Nick, we're totally cool with you not doing this very often. Keep it up ... or off.
