Four ab exercises that are way more fun--and way more effective--than crunches.

We've co-opted key moves from one of the country's hottest fitness programs: Core Fusion, a strength-training regimen that has attracted such A-listers as Cameron Diaz, Charlize Theron, and Kate Hudson.

"People come to Core Fusion because they get results," says cofounder Fred DeVito. "You get leaner and more toned, but the workout remains challenging, so you continue to get better and better results." (Find a Core Fusion class, taught exclusively at Exhale Spa, or buy a DVD at exhalespa.com.) Do these four Core Fusion moves three or four times a week—you can add in two weekly cardio sessions to boost the bodyshaping benefits.
