Hi, my name is Jocelyn Thompson-Roll. I'm a peloton instructor and I teach running and bootcamp

classes on the peloton tread. Don't get caught up in the amount of time that you have to spend

doing something. You don't need to do 30 minutes or 60 minutes for it to count. Five minutes can

Start small and don't shortchange yourself. The Guardian Labs has partnered with peloton to help

you find motivation that moves you. To find out more, visit thegardian.com-forthslash-motivation

on the business of telling forged art from authentic art. And when I met him, I found he had stories,

so many stories about working with the FBI or about art forgers he'd unmasked. The techniques he

used were in themselves fascinating to me because the science fascinates me. But the story also

indulged my passion for the history of art. It gave me an excuse to sit in the library and read

through old books about art forgers. And it gave me an excuse to think about this notion of
