Gary LeVox from Rascal Flatts has a personal fitness trainer named Wes, and he has a secret about the country star that he’s sharing. In order to stay in shape on tour, LeVox has the latest infomercial craze, the Shake Weight, on his bus.

"Y'all can make fun if you want to, but the Shake Weight is the real deal, I’m telling you," LeVox insists in the video, which was uploaded to YouTube. "I don’t even have the man version -- I got the chick version, like two-and-a-half pounds. It looks weird, I know. Don’t say anything. It works."

And to prove it, in the video he flexes his right bicep. The last shot leaves us with the 'I Won't Let Go' singer's best body builder pose, complete with appropriate grimace.

As previously reported, Rascal Flatts are currently on their Nothing Like This Tour, which kicked off last week with Chris Young and Luke Bryan. There also might be new babies on board from time to time, as guitarist Joe Don Rooney’s wife Tiffany had daughter Raquel Blue on Sept. 7 and bassist Jay DeMarcus’ wife Allison had their daughter Madeline Leigh on Dec. 17.

This past weekend, the guys taped their live show from St. Paul, Minn.'s Xcel Energy Center that will air as a special on March 12 on ABC.
