Curious to know how celebrities squeeze fitness into their daily lives? Want to know the secrets of the stars? Bi-weekly our That's Fit fitness expert Fitz sits down with the celebs we want to know more about, and digs out their great and not-so-great methods to staying healthy.

While spending time backstage with the mega stars of teeny tot entertainment, I had the chance to figure out how these amazing men from Australia have kept themselves in such great shape. Dancing, jumping, and flying across stages (sometimes twice a day) hundreds of times a year and well into their forties does not come easily. Murray Cook is the red Wiggle who loves to play guitar. Fortunately for him, he also loves to stretch. He took me through the series of back stretches he completes on a daily basis, and in my expert opinion ... his routine is awesome! Back injuries both minor and major seem to bother all of us at least once in our lives. Many of those injuries could be prevented with a simple and consistent stretching routine like the one Murray demonstrates here.

On a personal note, Murray was a pleasure to work with. At 6'5", he's a gently giant no doubt. Funny too. He along with Sam, Jeff, Anthony, and Captain Feathersword (Paddie Paddick) each take great care of themselves. I adore The Wiggles; I believe they have lots to teach to both children and adults. Maybe I can con them into doing some fun fitness videos with me for the Moms and Dads too!
