“The Ranch: Home of an American Sports Dynasty,” a one-hour documentary exploring the Karolyi Ranch, a U.S. gymnastics national team training center, and chronicling the making of the 2016 Olympic team, will premiere on NBC on Friday at 8 p.m. ET.
Bela and Martha Karolyi defected to the U.S. in 1981, after training gymnasts in Romania such as 1976 Olympic all-around champion Nadia Comaneci.
Since the mid-1980s, the Karolyi Ranch in Huntsville, Texas, has been a training ground for U.S. Olympic champions such as Mary Lou Retton and Kerri Strug.
