The gluteus maximus, the body’s largest muscle, plays a pivotal role in maintaining spine stability and upright posture. However, prolonged sitting can weaken this muscle, causing tight hip flexors and reduced hip rotation. This dysfunction can lead to chronic joint pain and problems with the sacroiliac joint, which, when compromised, may result in lower back pain. To address these issues, exercises such as the Couch Stretch and Piriformis Stretch can alleviate tightness and restore hip functionality. Additionally, strength training exercises, including Barbell Hip Thrust, Sumo Deadlifts, and Good Mornings, can effectively target and fortify the glutes. Properly training the glutes can not only enhance athletic performance but also prevent potential spinal and joint issues.
