"Just how strong is she?
Impossible to tell, because her father only allows her to show about
75% of her maximun strength for safety reasons. The father, Uri, will
not allow Varya to strain, so most lifts she does to set strength
records are done will relative ease. Examples of her strength include
at age 10 flipping her father to the mat in wrestling training and at
age 10 easily carrying 3 small people on her shoulders."
"Just how strong will she be?
Impossible to tell. As she gets older, how strong she will be three
years from now is impossible to tell. Her fathers believes by age 12
she was stronger than him, Uri is a professional circus strongman who
weighs about 250 lbs (115 kilograms)"
Why would "her fathers" believe she was stronger than him?
