This card set is intended to provide the user with quick and easy mobilization, stretching and muscle relaxation exercises. The exercises are easy to understand and can be completed at the working place. I focused on the lower back when choosing exercises because many people experience acute or chronic back pain in that region. Sitting a lot in the office or in class at school, or getting used to wrong postures can lead to back pain. These exercises are intended for everyday use and are a break and relaxation for the person who does them.
