Study Arms:
- Yoga (Type: EXPERIMENTAL): The yoga intervention will consist of 2x weekly, 60-minute Hatha Yoga classes for 12 weeks, geared toward a CLBP population. Classes begin with a few minutes of simple seated breathing exercises. Depending on their mobility, participants can sit either on the floor or on a chair. This is followed by gentle warm-up stretches. Participants are then led through a series of standing postures, seated postures and floor postures. The difficulty of the poses will gradually increase over the duration of the 12 weeks, and appropriate modifications are offered to participants whenever needed. Deep and rhythmic breathing will be emphasized throughout. Each class will end with a supine resting pose.
- Delayed Treatment Control - Usual Care (Type: NO_INTERVENTION): Participants randomly assigned to this arm are allowed to continue all existing treatments. Participants and their primary care physician are asked to not change treatments unless medically necessary. participants are asked to not do yoga for 6 months. They are given free yoga and a yoga mat after 6 months.

Based on this trial design, predict the completion outcome and termination type (if applicable).
