Sometimes it seems we can spend hours in a gym and see little results. But a wildly popular infomercial product claims to get you buff--without wasting time. One local DJ tried it and tonight he helps put P90X to the Tuesday Tryout.

The P90X infomercial promises to whip you into shape with good old fashioned hard work. Something its creator says our nation desperately needs. "People are unhealthy, overweight, and obese. They're struggling." I recently sat down with Tony Horton --who's almost become a household name. He's sold 2 million copies of his 12 dvd workout series.

"It will put you in the best shape of your life," says Jeff Walker.  The KRZ DJ  worked out --but wasn't making huge gains. So he turned to P90X. "It requires you to work your butt off for 90 days." This was what walker looked like three months ago. Here's what he looks like now. 15 pounds lighter. "I have muscle definition for once in my life...most of my strength doubled in 90 days."

So what's the secret? Changing your exercise program so your muscles don't adapt. "It's that confusion that makes you sore. Makes those muscles gain strength even quicker." Drew Flavell is an athletic trainer for Geisinger. He's been through the program and says it's geared for men and women of all ages. “He makes adaptations to it where you can start with lower reps or weights and work yourself up"

Horton says "we're not all fake and glitzy and smoke and mirrors." Tony says P90X is all about hard work and eating right.

Jeff Walker is thrilled with how he looks --but he's even more excited that his cholesterol dropped forty points. "I feel the youngest I've felt physically in about 2 decades, right now at 52 I feel that way." So P90X muscles its way up the Tuesday Tryout.

P90X costs about $120.
