Gilbert Arenas has undergone three knee surgeries in the last 18 months, but looked close to 100% at Barry Farms Recreational Center on Friday night.

The Washington guard was seen attacking the basket and even dunking effortlessly without wearing a brace on his balky knee.

Arenas has been working out with renowned trainer Tim Grover, who has worked with Michael Jordan and Dwyane Wade.

The Washington Post also reports that Arenas has lost weight and that he may even be down to what he was when he entered the league.

Reports indicate that Arenas is close to 207 pounds.
