Jason Priestley Back To Full Fitness

Former Beverly Hills 90210 star Jason Priestley's injuries from his horrific racecar crash are fully healed - even though it happened just five months ago.

The actor was spotted at the 24-Hour Fitness and Sport gym in Hollywood, California, where he appeared to be back in finest form.

A source says, "He had good color, and he's put on weight. He worked out like a freak for two solid hours."

Last August, Priestley careened out of control on a Lexington, Kentucky, race track and slammed into a wall at high speed. The actor sustained a broken back, concussion and a broken nose, among other injuries.
