You may have been a fan of Jennifer Garner's fit physique from her days on the TV show, Alias. Through multiple movie roles and even pregnancy, Garner has followed a smart and consistent workout plan to stay in top shape.
In an interview in Star magazine, Garner said she has worked back up to cardio and strength training 4-5 days a week. She credits her personal trainer with helping her plan a workout regimen. In addition, Garner said that she strives for moderate-sized meals that are generally high in protein and low in carbohydrates, along with plenty of water.
Jennifer Aniston's favorite workouts include cardio, too. According to an interview in Self magazine, Aniston favors interval workouts on an elliptical trainer, alternating 1 minute of high intensity work with 2 minutes at a moderate pace for a total of 22 minutes. One of Aniston's favorite workout routines combines holding a yoga pose for 30 to 60 seconds and following each pose with 2 sets of 8-10 reps of calisthenics.
Cardio should be part of your overall workout plan, but how hard do you need to work? If you're not into using a heart rate monitor, use the talk test. If you can carry on a conversation without getting totally winded, you're fine for most maintenance cardio workouts. Obviously, you want to do your interval workouts with more intensity (about 80% of your maximum). And make sure you alternate hard workout days with easier days to avoid burnout.
