Elizabeth Morrow has created Yoga by Numbers.
The oversized yoga mat is dotted with big, numbered circles.
An instructional DVD tells beginners where to put their hands and feet.
Morrow is an athlete, a skier and soccer player who suffered a lung collapse.
She is also a certified yoga instructor.
After her health scare, Morrow says she wanted to make yoga more accessible.
Traditional yoga teachers say they welcome the mat as a way to get people interested.
