Tupler Technique®

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 to: 

  • past, previous, or current pregnancy 
  • excess weight around the abdomen 
  • performing exercises and simple activities of daily living incorrectly  

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 use the Transverse Abdominus (your inner abdominal muscles or "core") properly during every day life and exercise. You will also learn how to live core strong by practicing proper posture and alignment. We will address how to perform activities of daily living correctly and if you have diastasis, heal the connective tissue that joins the outermost abdominal muscles known as the rectus abdominus. Healing the connective tissue is all about putting it 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.

How Ab Separation Rehab can help?
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.
