Katy Bowman of the Restorative Exercise Institute discusses how to really strengthen your pelvic floor. In the article, Katy explains overactive pelvic floor and how it relates to the gluteal (buttocks) muscles and the sacrum. People with overactive pelvic floors need pelvic floor lengthening and relaxation techniques to calm the muscles and the Central Nervous System (CNS).
There is a time and place for pelvic floor muscle strengthening. Kegels are helpful when there is pure weakness in the muscles and tissues without shortening or tightening.
Skeletal misalignment needs to be addressed in both the underactive and the overactive pelvic floor in order to address any muscle imbalances, that could be causing weakness and/or overactivity.
All of this is described in my book, Heal Pelvic Pain, and many exercises and manual techniques are explained however seeking out an expert pelvic floor therapist is essential to assess and treat the dysfunctions.
