Hey Mama! For the first phase of the 4th trimester we recommend that you only do low impact cardio and really stick to the 4th trimester schedule. This is so you establish correct breathing pattern and connect to engaging your pelvic floor and tva correct. Then in phase 2 if you do not experience any signs of intolerance such as; leaking, conjoin/doming/tenting, pelvic pressure, low back pain, ect - then you can add in higher impact cardio and other workouts. Just be very cautious of adding in something beyond you capabilities. There is no shame in modify and taking more time to rehab your core - that is the BEST!!
