Title: Extremely happy so far
Review: I'd like to echo what others have said about this video: it's clear, well produced, and extremely effective. I've been doing Phase 1 for about 6 weeks, and I can see increases in ab and core strength each workout. (This is partly due to my starting in a rather untrained state.) In the past many ab exercises have given me lower back pain, but I've been fine so far with this workout.Like the previous reviewer, I had to pause the video during the first several workouts to get the movements right. I also initially found some exercises extremely difficult to do at all. Don't let these obstacles dissuade you--they will go away with practice. For example, Phase 1 includes a side bend for which I could barely hold the starting position at first; now I am doing 7 reps per side, and adding 1 rep per week.
