Alexander Skarsgard wrapped up a workout at Equinox on Friday in LA and left the gym in a very tight shirt. The actor has been focusing on his fitness for the past several months as he works on True Blood, which returns on June 26, and keeps up a busy modeling schedule, having posed for the covers of both Interview and GQ's latest issues. Alexander has more than just his popular HBO series to promote with two of his big-screen projects, Straw Dogs and Melancholia, out this Fall. In the meantime, though, fans of the bloodsucking Eric Northman will be glad to see one of TV's top vampires back on the small screen. Several of True Blood's stars will be at Comic-Con next month in San Diego, and while Alexander won't be joining the panel, Anna Paquin and Stephen Moyer are both slated to attend.
