She’s a two-time Dancing with the Stars champ, but Kym Johnson took home a trophy more valuable than the coveted mirrorball after falling for her Season 20 partner, Robert Herjavec, 53.

Things with the couple of over seven months are “really really good,” says Johnson, 39.

“He’s very sweet. I’m really happy,” Johnson tells PEOPLE. “Robert just has so much passion about everything he does which is just so great to be a around. He’s just very positive. I think that’s why he’s so successful in everything he does. When he does something, he commits to it totally. He did that with Dancing. He’s not afraid to go there and look silly if he has to!”

Now, the Australian DWTS pro is bringing her unique talents of molding would-be dancers skills to fans everywhere, with her fitness brand 5678 Fitness and the upcoming releases of her fitness DVD, 5678 Fitness and book, The 5678 Diet.

“Not everyone can do six hours of dancing a day,” says Johnson. “But I take the dances we do on Dancing with the Stars and make them a workout. You’re having fun. You don’t actually realize you’re working out and that’s the key to it.”

And dancing hopefuls with two left feet needn’t worry.

“You don’t need to be a dancer to do [the workouts],” says Johnson. “We start off with the basic salsa and the cha-cha. It’s an easy introduction and then it builds. Plus with the DVD, you can do it at your own pace.” After all, she says with a laugh, “I turned Jerry Springer into a dancer! If he can do it, anyone can!”

The 5678 Diet and the 5678 Fitness DVD will be released Jan. 19.
