Tamilee Webb, Tracy York and Donna Richardson are fantastic. I have other tapes from all three instructors, but this is still my favorite. The aerobic routine is challenging, but easy to pick up after a few tries. The toning session is very effective without being too painful, although it does get a bit repetitious toward the end. All in all, it's a great tape and definitely one to add to your fitness collection!You had better know magic This tape is too difficult to keep up with, it has too many dance moves and it is too hard to catch on to. I prefer a step tape, most people especially beginners would have a hard time and would most likely give up trying to use this tape.
