Diastasis Recti is a Separation of the Rectus Abdominus or Outermost Abdominal Muscles. It is caused by force or pressure on the connective tissue that joins the rectus abdominus muscles.
Cheryl specializes in working with Females and Males of any age who have a weak or 
dysfunctional core, and/or diastasis recti or have undergone surgery to repair a diastasis due 
but not limited to: 

  • Past, previous, or current pregnancy 
  • Poor posture 
  • Performing exercise and simple activities of daily living incorrectly
  • Injury


Rebuilding and strengthening your core and/or closing a Diastasis is possible. 
In the vast majority of cases, surgery should not be required. 

You will learn how to rebuild your abdominal muscles by retraining your Transverse Abdominus (your inner abdominal muscles or "core") to properly function.  In 1-3 sessions you will learn to rebuild your core by doing a few simple things every day: (1) a minimal amount of daily therapeutic exercises, (2) integrating your core into your activities of daily living including getting up and down properly and practicing proper posture and alignment, (3) splinting or taping if needed, and/or (4) incorporating your strong and rebuilt core into safe and effective fitness practices if you exercise.

If you have diastasis, we will also work on healing the connective tissue that joins the outermost abdominal muscles known as the rectus abdominus. Healing the connective tissue is all about putting the connective tissue in a better (or narrow) position to heal, bringing blood flow to the area, protecting the area and eliminating intra abdominal force and pressure on it when doing any type of activity. 

Using the Tupler Technique® as a foundation for treatment, Cheryl will teach you the skills to become "core strong" for the rest of your life. Cheryl offers services in the San Francisco East Bay and occasionally travels to Newport Beach to train clients.

What is an Ab Separation? 
How do I know if I suffer from a weak or dysfunctional core and/or diastasis recti? 
(If you answer Yes to any of the questions below you are a candidate to work with Cheryl)
How do I heal my weak Core or Ab Separation?
Cheryl Williams Bjornson,
Corrective Exercise Specialist, Personal Trainer & Official Provider of 
the Tupler Technique® 
The outermost abdominal muscles are the support system for your back and organs. When the muscle separates, the connective tissue stretches sideways, which weakens the support for your back and organs because they are now supported by the connective tissue and not your muscles.
