Jennifer Aniston, who is now 47 years old, works out every single morning, seven days a week. Aniston states, ?I?ll go do a workout of some sort. I have a trainer, a wonderful woman who I do this spin-yoga class with. We spin for half an hour, and then do yoga for 40 minutes. That?s pretty intense. Then I go to a gym, where I do strength training and just my own thing on the treadmill, the bike, or the elliptical, just to change things up. Keeping your body confused is always the key for me.?
