Jake Gyllenhaal & Austin Nichols Hit Gym with Sophia Bush

Jake Gyllenhaal works up a sweat during an intense two hour work-out on Saturday afternoon (May 29) in Los Angeles.

The 29-year-old actor was accompanied by One Tree Hill co-stars (and real-life couple) Austin Nichols and Sophia Bush.

Jake and Austin used to bike together all the time and have been hitting the trails since at least 2006. They look quite snug in their spandex together!

Jake‘s new movie, Prince of Persia: Prince of Thieves, opened in theaters this weekend. It debuted at #3 at the box office with $30.2 million behind Shrek Forever After and Sex and the City 2.
