Nick Jonas' Workouts Are Clearly Paying Off - See the Photos!

Nick Jonas puts his massive biceps on display while wearing a tank top on his way to the Heart & Hustle gym on Friday (December 1) in Los Angeles.

The 25-year-old singer always tries to keep in shape and you can tell that his workouts are clearly paying off!

Nick left the gym in a maroon leather jacket and he was seen later that evening stepping out for a night on the town in that outfit.

Nick played a Jingle Ball concert on Thursday night, but he sat out L.A.’s show on Friday.

FYI: Nick is wearing a Maxime Hernandez tank and APL running shoes.
