Workout #119-08 Day #171 P90X Shoulders and Arms this morning.. I need to start doing some sit-ups again. I know they helped before. I need to combine what I used to do at the gym with some of the items from ab-ripper X. FitnessRandy ZabarskyJune 19, 2008Comment Facebook0 Twitter LinkedIn0 Reddit Tumblr 0 Likes
