Jennifer Aniston was recently seen leaving a workout in Los Angeles looking incredibly fit. The 54-year-old actress wore sleek black leggings that showcased her toned body and some red flip-flops from Havaianas. Her tank top advertised Stand Up To Cancer, a charity event she has previously participated in. Her famous caramel blonde hair flowed freely in the wind, while she held a red sweater on one arm to protect herself from the sun’s rays. Jennifer completed her look with a pair of blue-tinted sunglasses.
