Enter the Infrasternal Angle (ISA)

infrasternal angle training

Michael Kay graduated from Chapman University in Orange, CA with a Doctorate in Physical Therapy. Upon graduating he worked in various outpatient clinical settings and became extremely dissatisfied with standard outpatient orthopedic practice. Repeated clamshells, “bandy” exercises, all along with the pressure to slam more patients into an hour than was humanly possible made Dr. Mike sad. This made him to look outside of the standard PT practice and run far away from the insurance model never to return again.

Dr. Mike believes in a serious training approach along with appropriate manual therapy. He works all along the performance spectrum from early rehab to the highest levels of performance. He practices and trains clients at Premier Fitness Systems in Scottsdale, AZ. He is available for online coaching and custom program development.

    Mike, thanks for the presentations. I have seen Bill Hartman and others speak on this topic but everyone has a slightly different way of presenting it. I find that helpful in understanding it better. I have a question vis-a-vis the different presentations you presented. I personally have a wide ( based on the testing that I have had done by other PT’s ) ISA. In that scenario, you said that all curves are increased. However, in my case, I have a very flat T spine and straight C spine. Can you explain that presentation to me please??

    Hi Larry. Thanks for the great question. I would guess you have a compensation on top of the wide ISA. So… you are pushing air into anterior chest and extending through mid/upper spine. This will flatten the areas where you’re flat… you have essentially taken t2-7 and bent backwards, prob w military posture in cervical spine. Just strategies to get air in… commonly seen in populations that have lifted heavy weights… ie power lifting posture w bench press. Start w wide ISA resets… make sure you ISA is dynamic and then can work w back to wall and reaching for a chair… quiet pecs and breathe into the posterior mediastinum. Let me know if this makes sense. Thanks again for the question.
