Russell Crowe is using a $120,000 gym on the set of "Robin Hood" to avoid being a chubby hero.

A fat, aging Robin Hood would make an interesting and perhaps great movie......

Exposay: Russell Crowe is using a $120,000 gym on the set of his movie to avoid gaining weight. The 45-year-old actor is so desperate to stay svelte while filming "Robin Hood," producers have installed state-of-the-art exercise equipment in his private trailer so he can work out when he is not shooting.
A source told Britain's Daily Mail newspaper: "Russell is a professional. He knew he was cast to play Robin Hood, not Friar Tuck. He knows he has to stay fit."
Russell spends hours each day locked in the converted motor home, lifting weights, boxing, jogging on the treadmill and cycling.
The star has been on a strict diet and exercise regime for months to prepare for the film. He has reportedly lost almost 20lbs.
Crowe stars alongside "The Curious Case of Benjamin Button" actress Cate Blanchett, who took the role of Maid Marion after Sienna Miller withdrew. Kate Winslet and Rachel Weisz were also considered for the role.
Filming will continue until August and the movie is due to be released next year.
