As usual, Jillian Michaels' workouts are interesting, tough, give results very quickly, and as she likes to say "delivers results." I love how her workouts will leave you noticing muscle toning after the first week or so. It's super motivating. This workout DVD is tougher than her 30 day shred one, which means you might have to slow down a bit at the beginning. In fact, it can be a bit difficult to progress from level 1, but it's still fantastic! I really love the typical interval training that Jillian uses. In this DVD the workouts are about 30 minutes long each, which is still manageable, although I loved that the 30 day shred ones were 20 minutes long. One thing to notice is that the cool down time that she prescribes is never enough, not for 30 day shred, and not for this one. You need to do about 10 minutes of stretching afterwards to avoid too much soreness (oh yes, you will still be a bit sore!). Other than that, it's a fantastic, motivating, entertaining, awesome workout DVD. Don't hesitate to buy it!
