I am overall very pleased w/this workout! It has a couple of minor flaws such as the music is a little louder than Michelle @ times and the video production quality isn't as nice as others. That being said, I am very glad to have purchased this DVD! It is similar to Jari's with higher reps and longer sets but still has it's own unique quality. It is however not as many reps as the typical Jari workout. I felt my muscles burning from the start and it offers level variations for beginner-advanced. Up the weights for a greater challenge. Her form is excellent and she is a an upbeat instructor. Happy to try her other 3 very soon and looking forward to future releases!
