There’s no questioning Rory McIlroy’s passion for the game but it seems his passion also for working out in the gym is just as intense.

And girlfriend Caroline Wozniacki says McIlroy’s desire to push his physical well-being to the full has a positive spin off on her own well-being.

”Even in my off season I’m like saying, ‘Can you just rest for a second? I don’t want to see the gym. I don’t want to hear about the gym. I don’t want to go run. I just want to relax,” said Wozniacki.

”He’s like, ‘No, but let’s just go to the gym.’ But it’s good fun.”

In this interview with AP the Danish tennis ace says that McIlroy’s desire to push his conditioning to the limits has increased ever since the pair first got together.

And Wozniacki said she suggested the idea of getting him out of the gym and spending 25 minutes of running in Monaco before heading to the gym together.

”It was quite hot out there. After 15 minutes I could really see he was struggling out there,” she said.

“But it’s great that we can motivate each other. It’s great that we can do so many things together.”

In fact, Wozinacki says she’s so taken by McIlroy’s efforts on the practice range she’s a right mind to join him even if her golf game is not near as good as her tennis.

”It goes well for a while,” she said.

”Then once it starts going downhill I take a little break and watch him hit some balls. I think, `That looks easy.’ I take a water and then I go back at it, and then I need a few pointers from his coach or caddy. It’s a frustrating game, but I really enjoy it.”

By the way, Wozniacki echoed McIlroy’s recent comments that rumors of the two possibly breaking up aren’t true, and that the couple are doing just fine: “‘Everything on that front is great,” she said.

In fact, she added to AP they plan to get together next week in Miami, where the WTA Sony Open will take place – and take in a daily run together.
