Washington, Jun 20 : American model/actress Devon Aoki has revealed that when she entered the world of films, she was made to tone up her muscles by training with a 30-pound gun.

Aoki, 26, who decided to take a turn at acting from her catwalk career, had to beef up her body for her role in "Mutant Chronicles".

"I had to pump my arms up quite a bit. They were a little on the weak side when we started and by the end of filming, I was pretty rock solid," Fox News quoted her as saying.

"The funny thing was most the boys got dummy guns that weigh very little, and I got the real McCoy!

"I was running around with a 30-pound gun under my arm for the entire film. That might have been their way of telling me I needed some muscles!" she added. (ANI)
