Over 100 men and women joined a yoga class at Ottawa's Richellieu Vanier Community Centre, held simultaneously with similarly massive classes taking place in 20 other cities across Canada on Mar. 4.

The 1-hour yoga class, lead by yoga instructor Jessica Keats of YogaFit was part of the Power of Movement national initiative to raise funds for arthritis and autoimmune conditions research.

The Power of Movement initiative started in 2005, and has raised over $1 million to date.
