Knee-to-Chest Stretch
By Oliver Wakefield-SmithLast reviewed 2026-08-021 primary source cited→ AboutKnee-to-chest is a common, low-effort lumbar flexion exercise. None of the studies in our references tests it on its own. The wider evidence concerns whole programmes: a review of 43 chronic low back pain trials (Hayden and colleagues, 2005) concluded that individually designed programmes, including stretching or strengthening and delivered with supervision, may improve pain and function. The authors note that many of the studies were low quality.
