It plays a major role in: Pelvic stability Side bending and trunk control Load transfer during walking and standing 🔒 How QL Spasms Affect the Hip When the QL becomes overactive or spasmed, it can: Pull the pelvis into subtle asymmetry Limit hip range of motion Create the sensation that one hip “won’t release” Refer pain into the hip, low

Why the Dead Bug Works: Functional Core Strength The Dead Bug exercise targets the transverse abdominis, rectus abdominis, pelvic floor, and spinal stabilizers without putting excess strain on the lower back or neck. ✅ Key Benefits: Improves core stability and spinal alignment Builds strength in abdominals and hip flexors Enhances neuromuscular coordination Supports lower back health Safe for people with back pain when done correctly Improves posture and balance Helps preven

Tightness in the deep hip rotators — including muscles like the piriformis, gemellus, obturator internus, obturator externus, and quadratus femoris — can contribute to pain, limited range of motion, and issues like sciatica or general hip discomfort. The video linked above offers a clear demonstration of how to release these deep hip muscles using specific manual or self-release techniques, helping restore mobility and ease muscular tension.
