The knee hug stretch brings both knees toward the chest while lying supine, creating a gentle flexion stretch for the lower back. This simple position relieves compression in the lumbar spine and stretches the erector spinae muscles. The optional rocking motion adds a gentle massage effect to the paraspinal tissues.
When to use it
Use first thing in the morning or after long periods of sitting.
Who it's for
Anyone with lower back tightness, desk workers, and those seeking gentle morning mobility routines.
Keep your head and shoulders relaxed on the floor—there is no need to curl up. Focus on breathing into your lower back, feeling the expansion with each inhale. The gentle side-to-side rock should come from your hips, massaging the sacrum area.
