Hi Joe, first i just want to thank you for the response it is very much appreciated and is what makes this app/site so awesome. Cant say enough good things about your content.
My wife does not have any issues with tva or pelvic floor it was more of ways she could activate the tva muscles in preparation for birth.
We did some research that TVA activation will help and she does some excercises but feels like she is not engaging the right muscles. It may be like you said that it is just a much different feeling than what she is used to that she thinks there is no activation in the tva. I showed her the activation videos you have posted and thought maybe you had some other activations that you may have worked on with your wife or other clients that helped. Again thanks so much!
