Tight Hip Flexors and Quads Can Coincide with Anterior Pelvic Tilt
In anterior pelvic tilt, the legs will have tight quads and/or hip flexors and lengthened/weak hamstrings and glutes. In the trunk, lower back muscles (erector spinae) will be tight and abdominals (rectus abdominus) will be weak. This affects a wide range of the population due to the amount of time we spend sitting. Though there are many causes of lower back issues, excessive anterior pelvic tilt will often result in lower back problems.
Normal pelvic tilt for men is 3-5° and for women 5-7°. This angle is measured with one point being the posterior superior iliac spine (PSIS) and the other being the anterior superior iliac spine (ASIS). For an accurate assessment of pelvic tilt, please consult with a qualified health or fitness professional.
