Jennifer Aniston was the picture of fitness when she was spotted emerging from a workout in Los Angeles this week.

The 54-year-old Friends icon slipped into a pair of sleek black leggings that emphasized her enviably toned physique, and which she paired with some red flip-flops from Havaianas. 

She threw on a tank top advertising Stand Up To Cancer, the biennial star-studded fundraiser she herself has participated in before.

Her caramel blonde locks, which became world-famous for her 'Rachel' hairdo on Friends, fluttered freely in the breeze.
