When it comes to knockout bodies at any age, Heather Locklear tops the list! The slim and sexy star recently turned the big 5-0, but that clearly hasn't stopped her from rockin' a fabulous figure and cool confidence to match.

Gracing TV screens and magazine covers for decades, Locklear always manages to look much younger than her years. How does she do it? Aside from those obvious good genes (yep, we're envious), the talented actress and devoted mom has worked out in the past with celebrity trainer Garrett Warren of Woodland Hills Athletic Club.

"Heather is one of the nicest people I've ever met, but also one of the most professional," Warren says. "She was always on-time, incredibly committed and very driven when it came to her workouts."

Warren, who boasts oh-so-hot celebs on his fitness roster like Kate Hudson, Jaime Pressly and Shannon Tweed, trained Locklear five days a week for three years.

"There aren't too many areas you can pick apart on Heather because she looks so amazing," Warren says. "In general, we just wanted to focus on the areas ladies like to focus on…glutes, triceps, waistline and lower stomach."

With Warren's vigorous workouts, consistency is key.

"The hardest, most important thing women over 40 don't get in their workouts is consistency," Warren says.

"Commit yourself for at least three months and don't give up on it! Just don't rush into things and do something big and hard right away - slowly build yourself up."

Whether you're over or under the age of 40, one thing's for sure – you'll look and feel young at heart with Locklear's workout, below:

You'll Need: A treadmill, a flat bench, and 3 to 5 lb. dumbbells.

How it Works: This workout for Locklear designed by Warren combines cardio and strength training done in supersets to work the shoulders, triceps, biceps, legs, glutes and abs (trust us, you'll be feeling it everywhere!).

After a five-minute stretch and 12 to 15 minutes on the treadmill to warm-up, you'll be ready to roll.


Dumbbell Flys

How to do it: Lie down on your back on a flat bench with a dumbbell in each hand. Make sure your head and back are well supported. Slowly extend your arms until the dumbbells are lateral to your chest on either side. Bring your arms up and over your chest until the dumbbells are close together, directly over your body. Then, return to the original position, with your arms somewhat extended laterally.

Dumbbell Kickbacks

How to do it: Take a dumbbell with your right hand and position your left knee and hand onto a flat bench. Keep your arm tucked into your side at a 90-degree angle. Slowly extend your arm out and keep your elbow in. At full extension of the movement, make sure to keep a little bend in your arm and all the tension on your tricep muscle. Slowly lower the dumbbell back to the starting position. Repeat with your opposite arm.


Dumbbell Shoulder Presses

How to do it: Hold one dumbbell in each hand at shoulder height, with the elbows pointed downward and to the sides. In this ready position, inhale. Exhale as you drive both dumbbells overhead until the elbows are fully extended.

Keep the head upright and in a neutral position. At no time should you bend it forward. Slowly lower the dumbbells to the starting position while inhaling.

Bicep Curls

How to do it: Hold a dumbbell in each hand and let your arms hang at your sides. Slowly curl both dumbbells up and try to touch them to your shoulders. While you are performing the movement, turn your palm outward and squeeze your biceps for a one-count at the top of the movement. Slowly lower the dumbbells to the starting position and repeat.


Walking Lunges

How to do it: Stand upright, feet together, holding two dumbbells at your sides (palms facing in). Take a controlled step forward with your left leg. Lower hips toward the floor and bend both knees (almost at 90 degree angles). The back knee should come close but never touch the ground. Your front knee should be directly over the ankle and the back knee should be pointing down toward the floor.

Push off with your right foot and bring it forward to starting position. This completes one rep. Next step forward and repeat with the right leg.

One-Legged Squat

How to do it: Stand on one leg, with the other leg out and in front of you. Hands are kept out to the side to maintain balance. Next sit back down, as if sitting on a low chair.

At this point, your hamstring/glute should be resting on your calf. From here stand up again.

Tip: This one's a toughie! For beginners, put one leg back on a flat bench and hold a bar for balance, then do little half squats. Your glutes and legs will still be feelin' the burn, we promise!


Leg Lifts

How to do it: Lie down with arms extended alongside your body, palms down. Keep shoulders, head and lower back against the floor. Lift your legs until they're at a right angle to the hips. Lower the legs slowly and stop within a few inches of the floor. Hold the legs in the air for two seconds. Slowly raise the legs back to the starting position and hold for another count of two.

Stomach Crunches

How to do it: Lie on the floor with your legs bent, your feet flat on the floor. Place your hands on the back of your head, or if you prefer, cross them over your chest. Lift your shoulder blades off the ground moving your elbows towards your knees.

Don't try to lift your whole back - just your shoulder blades. Squeeze your abs for a second. Slowly return to the starting position.
