The other two IMAX workouts are basically the same format, with 10 intervals including a step routine repeated 4 times (with minimal breakdown) followed by a blast. The length of these tend to be between 50 to 60 minutes.
It is definitely worth it to buy the other two, with IMAX 2 being my favorite. The nice thing about IMAX 2 and 3, is that Cathe breaks up the blast usually into two distinct moves, rather than the one move in the orginial IMAX. For instance, in IMAX 2 one blast includes doing knees around the world, and then hopping 8 times on each leg, and repeating the sequence several times. In the original IMAX, the blast is just the hopping on one leg, without the other move (knees around the world). I like the additional move because it breaks up the tension that occurs with repetition, but is still very challenging.
Hope this makes sense. And perhaps a video clip would have enough of a blast segment shown so you could see what I mean.
Also, LowMax is a great workout that is like the IMAX's but low impact. This workout only has seven intervals with the step segment parts more broken down. This is a 60 min workout and really targets the legs and glutes!
