" Katy Perry has revealed that she had to train for her latest music video. The singer admitted that she hired a personal trainer to get her in shape for her &amp;#039;Part of Me&amp;#039; visual, which sees her join the US marines after coming out of an adulterous relationship.   Perry told MTV: &amp;quot;I got on a meal plan. I&amp;#039;m still on that meal plan, although I cheat a little bit - I have to live! &amp;quot;I got a fantastic person to work me out and get me into really good shape. On the actual base, I did a lot of things. I flipped girls, I learned how to fireman-carry. I know how to carry my weight a little bit more.&amp;quot; However, the star confessed that there was one stunt she was unable to master and the director had to edit that particular shot in the video. Perry said: &amp;quot;One thing I can&amp;#039;t do, and I hope that there are other people out there that feel the same way, is climb a rope.  &amp;quot;Oh my gosh, it&amp;#039;s so hard to climb rope! It&amp;#039;s all about grip and arms. I tried five or six times on set, but I had to cheat that shot. My hands were shaking.&amp;quot; Perry&amp;#039;s &amp;#039;Part of Me&amp;#039; has reached number one on the US Hot 100 and is currently on course to top the UK chart this Sunday. &amp;amp;gt; Katy Perry Teenage Dream: The Complete Confection megamix debuts Watch the music video for Katy Perry&amp;#039;s &amp;#039;Part of Me&amp;#039; below:      "^^<http://www.w3.org/2001/XMLSchema#string>
