Nick Jonas' Muscles Look So Buff Even Before His Workout!

Nick Jonas is looking hot, hot, hot in these new photos!

The 25-year-old singer put his buff muscles on display while wearing a tank top on his way to a workout on Friday (December 1) in Los Angeles.

Keep in mind that this is BEFORE the workout and before he got his pump in!

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 APL running shoes.
