'I think people's perceptions of yoga has changed'

EUGENE, Ore. -- Each day more Americans are turning to yoga classes for a peaceful and healthy way to work out.

The diverse spectrum of yoga practices, from vinyasa flow to aerial, gives people the opportunity to find the one that fits them the best.

A majority of the 20.4 million people practicing yoga in the U.S. fall within the 18-44 age range, according to a 2012 study from The Yoga Journal.

Chelsea Knight, owner of Hard Core Yoga, leads classes at her Eugene studio.

"I think that there was a preconceived notion that yoga was chanting, and you had to be either really flexible or really strong to do it. I think people's perceptions of yoga has changed," said Knight.
