It’s safe to say Yumi Bai from Singaporean duo BY2 has achieved the perfect peach booty. The singer who is very much a fitness enthusiast, often shares her fitness journey with her fans through the countless gym selfies she uploads online. This time around, the 32-year-old showed off her super toned back. “Who says skinny people can’t build muscles?” she asked. Oh boy, if you’re still waiting for a sign to hit the gym before summer is totally over, well, consider this your reminder.
Here’s Yumi in a grey outfit and proudly showing off the results of her hard work at the gym. Check out that muscle definition highlighted by her criss-cross top and her grey leggings.

From the countless gym selfies on her grid, it’s no secret that Yumi likes to hit the machines frequently. In fact she credits exercise and fitness as what ultimately helped her build self-confidence. Aside from weight training, the star also runs to get her dose of endorphins and to bump up her energy levels.
Just months ago, Yumi’s seemingly thinner frame was a cause of concern from fans who were worried about her health. Many urged her to eat more and gain weight after the star shared on social media that she dropped a few kilos and is down to 42kg. “Recently, too many people have asked me why I’ve become so thin. I didn’t think anything of it at first, but then my weight dropped to 42kg. Even my famlily is very worried about me. I want to make it clear that I’m not deliberately abstaining from food. Perhaps it’s just my spirit is a bit tired” she once shared.

I’m so confused. Is that muscle? I thought those were bones sticking out. She’s a bit on the skinny side, but she looks good, and seems well endowed.

Technically you need a bit of meat that you can turn into muscle. Woman need a way higher body fat to be still healthy than men who can go very low. I’m sure she hadn’t had a period for a while.
Also I don’t know how much of this photo is real but the looks are not naturally possible for a woman. You can’t have only bones and skin on your body but your breasts and butt still are very well rounded. Also her waist is too small to fit her ribs.
