Ren tells Yahoo that she used to do things to please others, instead of putting herself first. Ren says that she's now trying to overcome this aspect of her personality, and wants to give her followers an authentic portrayal of herself. "I was a huge people pleaser; it's something that I had to overcome," Ren said. "I was creating essentially an illusion. It's not real. So, I was like okay, I don't really want to be part of an illusion anymore."

Ren is a mentor, and has her own community for wellness and fitness called We Are Warriors. Ren says that she was inspired to start this program because she wants to help and mentor other people. "I saw there was a huge lack of mentorship within the education system – that's how I have gotten to where I am, that's how I am who I am," Ren said to Yahoo. "We find pieces of ourselves within older people who have accomplished what we would like to accomplish, so if we don't have those reflections, then we don't know what to grasp onto, because we are just a product of our environment."

Ren may be an influencer, but she's not the influencer who wants to sell you products. She tells ELLE that she doesn't do paid ads on Instagram, and wants to focus on giving her followers an actual look into her life. "Any of the typical offers have all come to me, whether it's a product for tea, or teeth whitening, or weight loss. And these brands have a lot of money. But [paid posts are] the complete opposite of what I'm trying to do."

Ren is in great shape, and has a nearly flat stomach. She has that for a reason, as she does ab workouts each day. Ren posted her favorite, quick ab-workout on her YouTube channel. In it, she is seen doing ab exercises like Russian twists, bicycle crunches, flutter kicks, and scissor kicks. Ren wrote in the video description, "I try to do this every morning. It's quick, to the point, and you'll feel it the next day."

Ren tells NewBeauty.com that she makes sure that she keeps up her fitness routine when she's on the road. She says that she likes to find local places to either walk or run, and brings workout gear with her. "I have a rule, I take the stairs everywhere; I'll even skip the escalators in airports. I try to do things where I'm staying active all the time. I also like to travel with my TRX and do these really intense ab exercises with it. When I'm in the tropics, I use the beach as my gym. So, morning swims or running on the beach are my favorite."
