Cat-cow pose
Abs - Hamstrings - Glutes

- Get into position on the floor with your hands and knees supported on the ground.
- Contract your abs, hamstrings, and glutes at the same time to rotate your hips backwards, eliminating the lumbar curvature.
- When you return to the starting position, exaggerate the opposite movement, maximizing your lumbar curvature so you can feel the difference between the two positions.
