This workout strengthens your hips, spine, shoulders, and core. The main focus of this workout is strengthening your hips with big, long hip openers, and sustained backbends to help counter inactivity, such as a weekend off, a day of sitting, or just lower-back stiffness in general. Instead of focusing on stretching and relief, though, this workout focuses on strengthening the inactive muscles. This workout strengthens your hips, spine, shoulders, and core.
