Yes, you can do just the ReCORE program! Postpartum women can have a weakened core without much diastasis. However, if you are within 2 years post and have abdominal separation (2 or greater) or are immediately post-partum, I would recommend wearing it to help the connective tissue heal faster for more effective results. The FITsplint will help support, splint and protect the tissue while progressiing in core strength, stability and control with exercises.
