The 20-year-old, who plays Hermione in the Potter saga, was spotted dressed head to toe in Nike gear after working out for two hours on the campus of Brown University, Rhode Island.
And her new elfin haircut proved to be perfect for the gym, because of its low maintenance style that can transform from sporty to glam within minutes.
Despite the lengthy workout though, Watson looked refreshed as she chatted with friends around campus.
And the British beauty had two male friends trying their luck with the actress as they approached her for a chat.
One handsome student in tennis gear was no doubt comparing workout tips, while another in causal street wear tried his own tactic but Emma didn�t look amused.
The actress has openly spoken of her love for school life, saying it keeps her in touch with friends and reality.
�I was scared I wasn�t going to be allowed to have both a career and a normal life,� she said.
Even though she was named Hollywood�s highest paid female star in 2009, raking in �19 million just for that year, she is determined to maintain a normal life by attending university.
Earlier in the month she even posted on her Twitter page: �It�s great to be back at uni � having the best time! Good luck to everyone else starting school this week, Em x.�
