I did All Body Attack yesterday and I love it!! One of the best workouts of the year, imo! Fast moving and innovative, fun intervals and Sharon just keeps on going and going! Great core segment also - nice 85 minutes of my day!
I did Hi/lo Euphoria this morning, just the floor segment, not the step, and it was fun, dancy aerobics that reminded me of Christi and Marcus in style and tone. Not very hi impact, but my heart rate got up there. If you are not into the dancy, turning kind of workout I am not sure you will like it, but I find it a nice change from the athletic styles so prevalent these days.
I haven't done Gay's yet, but am anxious to do so. Those are the only ones I got.
