First, I would highly recommend you to see a Women's Health Physio for one visit at least. She can do a hands-on diagnose and internal exam to check the health of your pelvic floor.
But here are several differences seeing your physio regularly vs joining a holistic program to heal your DR
1) An experienced Women's Health Physio who specializes in diastasis recti is usually hard to find, and most often than not, you have to go on a wait list.
Almost all my clients have visited with a physiotherapist prior coming to me, and most of them say that the physio usually dance around the core, and don't focus enough on healing the DR. Some don't even oversee your exercise in the clinic, and give you a piece of exercise paper to bring home and follow, that's my case!
2) Be prepared to take time to travel to and from the office, and have a 45 minutes visit every week for several months . If you visit continuously for 3 months, you can roughly calculate how much it can add up.
3) Beside the 1 hour visit/week. What are you going to do the rest of the times before you visit her again? What if you don't know if you are doing the exercise right, what if you experience other symptoms? What if you want to do XYZ exercise? What do you do?
4) Physio focuses on rehabilitating your core, whereas with me I approach your core and total body holistically so you are going to heal your DR, get fit overall and lose weight. In addition, I also provide DR-specific nutrition guidance and meal plans.
Don't forget, I also have a team of Women's health physiotherapist in my network that I can ask your specific questions to them for feedback.
