Curious to know how celebrities squeeze fitness into their daily lives? Our fitness expert Fitz sits down with the stars and digs out their great and not-so-great methods for staying healthy.

Jill Wagner is the bombshell host of ABC's ludicrous obstacle course game show "Wipeout." We recently spoke, and she openly revealed how she'd fare on the course and why working out is a requirement of her job.

Fitz: The "Wipeout" obstacle courses are insane. In your opinion, do they require great strength and balance or just luck?

Jill: Well, if you look at some of our contestants ... I wouldn't say that some of them are the most athletic. I think that a lot has to do with balance and luck, though, because I've seen the most athletic people not even make it through the qualifier. Balance is probably the most important factor.

Fitz: Do you think weighing more could be an advantage?

Jill: I think weighing less is definitely a bigger benefit. The smaller people get across those big balls easier; maybe it's because they don't make such a great impact as they cross them. You know what happens to the bigger people (she laughs)!

Fitz: Have you ever done one of the courses?

Yes, we all do crunches. Crunches, crunches and more crunches. I do them myself, and think very highly of them. But! If you'd like to change things up and work on sculpting your fancy torso in new way, give these skills a try.

• Prone pikes. Place your feet on a stability ball or on some Gliding Disks, with your hands on the floor in push-up position. Back flat. Lift your hips straight up to the sky while keeping your legs straight. Once you've elevated your hips as high as they'll go ... lower back to push-up position. Repeat at least eight times. Add one rep each day you do these. Very advanced!

• Front kicks. Stand with one foot in front of the other with feet shoulder width apart. Lift the front leg by the knee first, and follow to extend your foot up high. You'll engage your hip-flexors and rectus abdominus as you raise that leg up high. Kick within your comfortable range at first, but challenge yourself to kick higher along the way. The higher you lift your knee, the more you'll work your abs. Switch your stance and repeat on the other leg. Kick at least 20 times per leg. Beginner to advanced level exercise, depending on how high you kick.
