There are seven hours left until tonight's performance. Samantha Wolfova walks between the school desk, which today consists of a round glass table next to the family's caravan, and the large circus tent. Inside, it's warm, the big fan roars and colorful lights in red and yellow spread shadows over the circus family as they warm up, stretch and take on the day's workouts.

Samantha arches her back in seemingly impossible positions. It's sweaty and some exercises hurt and she needs to rest in between.

What would your parents have said if you said you wanted to do something else?

"I don't know," she replies, smiling.

But she doesn't want to do anything else. She and her sister Andrea want to follow in the footsteps of their parents, and three more generations before them.

In the clip above, you get to see her show some of her exercises and hear about life as a circus artist.
