A simple exercise which eases tight or sore low back muscles. Perform multiple times throughout the day as needed.
Lie on your back with your knees bent and feet flat on the floor.
Flatten your lower back against the floor by tightening your abdominal muscles and tilting your pelvis up slightly. Hold your lower back to the floor for up to 10 seconds, then release. That’s 1 rep. Do 8 to 10 reps total.
