Who could forget Valeria Lukyanova, also known as The Human Barbie Doll? The Moldavian-Ukranian model first appeared on many people’s radars in 2013 when she was featured in a Vice documentary called Space Barbie. Earlier this year, she announced that she was going to partake in breatharianism. If you aren’t familiar, breatharianism is a practice in which people claim to live exclusively on light and air, instead of food and water. Potentially lethal pseudo-science aside, Valeria is back on our radar and it looks like she’s been putting in some time at the gym.
