The daughter of circus performers, ukrainian Varvara Akulova has been listed in the guinness book of world records and is often referred to as the strongest girl in the world. At just 4 years old she started lifting weights. By 10, she set a guinness record by lifting 220 lbs before smashing that four years later with a massive 660 lb. lift. Interestingly, Varvara doesn’t have the visible muscle mass you’d expect to see in someone so powerful. Experts believe she possesses special genetics, passed on from relatives who also demonstrated exceptional strength.
