Zac Efron was decked out in Nike gear for a run around his LA neighborhood on Saturday. He was looking a little more focused on his workout than the last time we spotted him jogging on the beach with girlfriend Vanessa Hudgens. Zac's getting in shape for a busy summer promoting Charlie St. Cloud, but it's his work in 17 Again that might make him a winner at June's MTV Movie Awards. Zac could be up for the golden popcorn in three categories — including Best Male Performance, which he won last year — when the nominations are announced on Wednesday.
