I have a very in-shape friend (think marathon runner and someone who is advanced in the strength area as well). She is interested in getting her core back in shape but does not have a dvd player so anything in book form or streaming form would be great. Something free too! I don't have children, but have read that diastasis recti conditioning is important instead of crunches. I've youtube'd a few but they all look pretty easy (at least by her standards most likely). She will definitely okay any exercises with her doctor.
Thanks.
Thanks.
