Jessica Simpson's Butt and Leg Exercises

You don't have to be a fan of Jessica Simpson's acting or singing to admit that she looked amazing in those Daisy Dukes for Dukes of Hazzard. Jessica Simpson's trainer, and creator of the 5-Factor Plan, Harley Pasternak, shared with us how Jessica Simpson got lean legs and a toned body while keeping her curves.

Harley Pasternak gave us this workout plan that you can follow so you can get a body like Jessica Simpson's. Do this strength and cardio workout five times a week.

Do at least 30 minutes of heart-healthy cardio five times a week, says Pasternak. Try cycling, running, in-line skating, and stair climbing, which all have thigh- and calf-sculpting payoffs.

• Lie faceup on floor with arms at sides, palms down, and calves on top of a stability ball.
• Engage abs and roll ball toward body with heels, lifting hips.
• Once heels are on top of ball, slowly roll back to start, lowering body to floor.
• Do 20 reps; 3 sets.

Cardio: Add some hills to your usual power walk, suggests Pasternak. "Incline walking activates your glutes and hamstrings, plus it's easy on the knees," he says. On a treadmill, set the incline to level 8, and walk at a pace of at least 3.5 mph for 30 minutes. Also try hiking, mountain biking, and climbing stairs.

• Hold for 1 count. Return to start. Do 10 reps. Switch sides and repeat. Do 3 sets per side.
