Meet Oxygen's managing editor Samantha Israel who, as it happens, took home the top prize in last year's fitness challenge here at the office. She's at it again, working out frenetically and trying to get those abs to pop! "My abs are my fitness benchmark. When I can see two to four of them, I know my routine is up to par. When I'm all belly, it's time for more weighted declines, reverse crunches and bicycles," says Sam, also Clean Eating's managing editor. Here she is kayaking in Westchester, NY.
