Post pregnancy work outs. what should or should not a woman do when her connective tissues are still soft?

Ease into it: Start with low impact activity (e.g. Brisk walking, limited cardiac work out, etc...) for the first 2-4 weeks following delivery. Generally speaking, by about six weeks post-partum, you should be good to go.

Wait: Exercise is for the biochemically fit. You have gone through a stressful phenomenon. Take it easy until you feel fit again.
