Hey Charla! That's great that you are aware of your DR. Pilates is a great way to close the abdominal gap. It helps to cinch the abdominal muscles back together. You will want to avoid things like planking, as it puts the pressure of the organs down into the tear, as well as extreme twisting (gentle twisting is totally fine). Exercises like seated core work with the ball behind your back is fantastic to help work into that connection.
I'm so happy you're enjoying my workouts! If you're every doing one and there is planking, avoid it, and in all the exercises really think about breathing the upper ribs down and lifting the abdominals in and up along the spine to find that transverse ab connection.
Let me know if you have any other questions! Thanks for the comment/question!
