Fergie Shares Celebrity Weight Loss Regimen

Perhaps you've noticed: Fergie is frickin' ripped.

Her concerts alone will keep her in decent shape - but you don't get that body without working out. Fergie and her trainer, Natasha, recently shared her awesome workout tips. Check it out below - and then get off the couch!

Cardio training: A half-hour, 3-to-5-mile run or a 45-50 minute 5-mile run. Not necessarily at a very fast pace, however.

Shoulders: Work the front and back of the shoulder, using 1.5-kg weights. Front raises for 2 minutes then side raises for 2 minutes, with as many reps as she can fit in. The key to this celebrity weight loss plan is to do a lot of them.

Biceps: Regular bicep curls using rubber bands. Stand with your feet apart, holding the handles so you do front curl with your arms very close to your chest. Do the right arm, then left, then both together - 20-25 on each.

Triceps: We lift a long bar on the bench as she lays back her back, for 20-25 reps. Then the fiancee of Josh Duhamel does as many tight push-ups as she can. It might be one, four or sometimes up to 25.

Legs/butt: Fergie's legs are so naturally toned, she can skimp on this (lucky), but she does do do squats - around 15-20, in three sets.

Yoga: Fergie does yoga on the ground to maintain her extreme flexibility. She does the "chair" pose and holds it for up to three minutes. Then the "warrior" one and two position for up to 2.5 minutes.

Abs: Start with basic crunches, then start adding things each time. At a certain point, she lifts her legs to a 90-degree angle, then straight out in front, with shoulder blades off the ground. About 20 in each.

Cool down: As with all celebrity workouts, it's important to stretch out afterwards. Whatever muscles she just worked out, Fergie stretches them out for at least 3 minutes while she relaxes and gets her breathing down.
