Now we know why the 45-year-old Entourage star, Jeremy Piven, looks half his age.
It looks like his secret is a combo of a healthy mind, body, and spirit.
The actor was spotted running with his trainer on the beach in Malibu this past Saturday, then leaving a Yoga class in El Lay on Tuesday.
Piven keeps himself hydrated too! He was grasping not one, not two, but THREE beverages while loading his yoga mat into the trunk of his ride.
He probably needed an extra boost after getting his butt beat by his trainer on Saturday.
Ha! Check out more pics of one of Hollywood's fittest stars below to see what we're talking about.
It looks like Jeremy couldn't quite keep up as much as he would have liked to.
We're just messin', we'll be lucky if we look half as good as this guy does when we reach his age!
