Title: Hard on Core!!
Review: This is a good pilates inspired workout on the ball. The ball really challenges the abs. This is not a beginner's DVD. If you are weak in the abs, MODIFY the moves. If you have a bad back, find something else. This workout needs a warm-up segment and a stretch segment. You will need to do these on your own.
