Paul Rudd: it's possible to look in good shape at 50.

Frank Grillo: He's 55. He trains every day, loves it and has always trained. He pays particular attention to 'core' body strength.

Penn Jilette: be prepared to eat lots and lots of vegetables and fruit.

Al Sharpton: He lost lots of weight over years. Now he's eating salads and smoothies. But these are store-bought smoothies. You can make your own (with less calories, more volume and variety) rather easily.
