I used P90X as a postpartum work out for an entire month, so I did 30 workouts. I quit because as a postpartum workout P90X is too rigorous. I was getting bruising from muscle damage, disrupted periods from the sudden change in activity and overall felt awful. I also found the time requirements a bit steep for a new mom, especially a new mom with a second child. The shortest P90X daily video or video combo is 45 minutes; most of the video are an hour to an hour in a half sometimes coupled with a 15-minute ab workout. Often laying the single mom role, as my husband works out on an oil platform for weeks at a time, over an hour each day just to workout was too much time for me to try to find.
