Seasoned yoga instructors Rodney Yee and Colleen Saidman demonstrate an array of seated and standing stretches and twists simple enough to be done at work -- or any time you need a low-key way to recenter your mind and body. Designed to relieve stress quickly in the midst of a busy day, the program includes 30 minutes of seated chair poses and 20 minutes of basic standing poses -- no need for a mat or other yoga gear.
