Jillian Michaels says evidence 'irrefutable,' trans athletes should not compete against girls

Celebrity fitness trainer Jillian Michaels joined 'Fox & Friends' to discuss West Virginia middle school students protesting a transgender athlete and her take on America's obesity crisis.  

Celebrity fitness trainer Jillian Michaels spoke out Tuesday in favor of fairness in women's sports after several middle school students in West Virginia staged a protest against one of their competitors, a natural-born male. 

Michaels argued the data supporting men's strength as superior to women is "irrefutable" during "Fox & Friends," even when accounting for cross-sex hormone therapy.

"You've got two competing goals in sports… One is inclusion, which everybody can understand and get on board with, however, the second goal that's in direct opposition with inclusion in this instance is going to be a fair competition," Michaels said on Tuesday. 

"And if that's your priority, if your overriding priority is going to be fairness over inclusion, you've got to turn to the data, and the data irrefutably shows that biological males are 10 to 30% stronger, faster, have better endurance, better aerobic capacity across the board."

At least five middle school girls refused to compete at the Harrison County Championships track meet last week after a transgender female won her shot put competition by three feet, according to the New York Post. 

The 13-year-old won the competition despite five girls from a rival school refusing to throw in protest of her participation.
