If I was going to fail in this role, I wasn’t going to let it be in a way that could have been prevented if I had worked harder.” Affleck added, “Getting ready for this role meant working hard, day in and day out. But it was the kind of work where I felt gains in not only my size, but also my mental and physical health.”

Rihanna loves to ride on a stationary bike, whereas some people will jog, walk, run stairs. Phase two is an upper-body resistance exercise, such as a back row or a shoulder raise. Phase 3 is a lower body exercise, like a skater lunge or a hamstring curl. Phase 4 is an abdominal movement like a side bend or a trunk twist. Phase 5 is a cardio cool-down for at least five minutes. So she'll do a continuous circuit, and each day of the week we do different body parts."

It’s like my weight is gonna go up and down, also we have these crazy beauty standards from... Instagram of people that are photoshopped or if they’re not photoshopped, it’s not every woman’s body.”

Singer Billie Eilish told The Guardian that she struggles with her body image, and social media plays a role in her mindset. “I see people online, looking like I’ve never looked,” she says. “And immediately I am like, oh my God, how do they look like that? I know the ins and outs of this industry, and what people actually use in photos, and I actually know what looks real can be fake. Yet I still see it and go, oh God, that makes me feel really bad. And I mean, I’m very confident in who I am, and I’m very happy with my life…I’m obviously not happy with my body.” Eilish added: “But who is?” Despite all this, Eilish still works to have a better view of her body. “We only need bodies to eat and walk around and poop. We only need them to survive,” she says. “It’s ridiculous that anybody even cares about bodies at all. Like, why? Why do we care? You know, when you really think about it?”
