Headed out to work on his physique, Justin Bieber hit up a local Equinox gym in Los Angeles, CA on Monday (November 19).

Coordinated in a red-and-black ensemble, the 18-year-old pop sensation sported gym shorts, a t-shirt, and a backwards baseball cap, while hiding behind sunglasses and his bodyguard.

The evening workout comes just a day after Justin took home three awards, including Artist of the Year, at this year’s American Music Awards.

Aside from bringing home new hardware, the Biebs had something else to be happy about.

As previously reported by GossipCenter, Bieber attended the event’s after-party with his mom and girlfriend, Selena Gomez, on his arm.

The red-carpet arrival came as a shock to some, since rumors have been swirling that the power couple had recently called it quits.
