7 Healthcast: Yoga injuries

The popularity of yoga has exploded in recent years with millions of people flocking to classes at studios and gyms.

But many of them don't realize just how physically demanding yoga is.

"If people don't understand the correct alignment and and practice thoughtfully and consciously, people can sometimes actually develop injuries," said Natasha Rizopoulos, a yoga teacher.

Orthopedic surgeon William Stetson says he has seen more and more yoga and Pilates students come in with lower back, knee and shoulder injuries- especially baby boomers.

"We know that as you begin to be over 40, 45 into 50, your muscles loose their flexibility and you have to be more diligent," Dr. Stetson said.

"After practicing for several months, my shoulder was in excruciating pain," said Shari Caine-Markus, a yoga student.

Shari didn't realize she was hurting herself in yoga, and even considered surgery.

But her yoga instructor helped her realize that she was collapsing her shoulders and straining her muscles.

"It didn't enter my mind before that there is a correct way and an incorrect way," Caine-Markus said.

There are some things you can do to avoid yoga and Pilates injuries- first start out slow and take beginner classes. Make sure you have a qualified instructor, and if you're feeling pain- stop, and if your pain persists see your doctor.
