Cassie was also so proud of the gold medals the US gymnastics team--AKA the "Fierce Five"-- took home at the Olympics because she really could relate to them.
"I admire them so much more," she said. "I really had to jump into those shoes [on Make It or Break It]."
While starring on the hit show about the competitive world of gymnastics, Cassie really understood what it took to go all the way the Olympics.
"I researched a lot about gymnastics and what they go through," she said. "They don't have normal lives. They have to train constantly and eat differently."

"Sad!" she laughs. "I was like, 'Why am I not there?' It was the first time ever that I missed my leotard!"
