I see this brought up now and again but It's such an under stated topic. Without the proper strength and flexibility in the hips, pelvis, and legs, the golf swing cannot truly release in the proper way. A lack in flexibility also affects spine angle and swing plane which again, are two major components in the golf swing. There was a great video posted on the Titleist web site that emphasized the importance of proper hip rotation, but they didn't really go into stretching exercises to help improve flexibility.
Can anyone chime in with some examples of stretching exercises for the hips/pelvic bone and lower body as it relates to golf please.
