Is targeting the quads the best way to reduce back pain? I tried this yoga routine to find out

I often deal with aches and pain in my back and lower body, mostly when I'm working at my desk. I do core workouts and hip-strengthening exercises to help with this, but I'm always looking for other options. 

Yoga instructor Adriene Mishler, known online as Yoga With Adriene, recently shared a routine to reduce lower back pain. In the flow, as well as opening up the hips, she offers exercises that stretch the quadriceps in the front of the thigh.
