Marisa Tomei developed a love for hula hooping while shaping up to play an erotic dancer in new movie The Wrestler because she found it to be the best exercise.

The actress stepped up her work-out regime as soon as she realized she'd be stripping in the film - and there was one routine that helped her tone up more than anything else.

She explains, "I hula hooped a lot, which is my favorite part of my routine...You're using your core muscles."

Tomei showed off her hula-hoop skills during an appearance on comedienne Ellen Degeneres' daytime talk show on Tuesday.

She also revealed she had to give "The Wrestler" co-star Mickey Rourke a naked lap dance in a scene on her first day on the set.
